Daniel Jackson's History
Daniel Jackson, Ph.D., is an archaeologist and linguist from Earth, and a member of Stargate Command's flagship team, SG-1.
Jackson was born on July 8, 1965. At age 8, Daniel lost his parents, Melburn and Claire Jackson, when they were killed in an accident at the New York Museum of Art. They were crushed while directing the relocation of massive stone blocks, effectively leaving Daniel an orphan. His grandfather, an archaeologist named Dr. Nicholas Ballard, had been too wrapped up in his own career, refused to adopt Daniel and as such, young Daniel was put in foster care.
Daniel eventually grew up to become an archaeologist, linguist, and expert in ancient writing systems, languages and cultures. He worked under Dr. David Jordan at the University of Chicago and met Dr. Sarah Gardner during his time there. However, he was ostracized from the scientific community for his radical theories involving the cross-pollination of ancient cultures and the Egyptian pyramids being landing sites for alien spaceships and were far older than previously thought.
Since his grants had all run out and he had been evicted from his apartment, Daniel was desperate for work when he met a mysterious elderly woman named Catherine Langford; she gave him a job translating ancient Egyptian hieroglyphs for the United States Air Force. After translating the coverstone found near Giza in 1928 and realizing the symbols he could not translate were in fact constellations, he determined that they represented a six-point destination. After briefing Major General W. O. West, he was shown the Stargate and he identified the seventh symbol. After dialing the address and sending a MALP probe, he convinced West that he could open the gate on the other side and he accompanied Colonel Jack O'Neil's team to Abydos.
After arriving on the planet and meeting several Abydonians working in a Naquadah mine, they were taken to the city where a feast was prepared while they waited out a sandstorm. The Abydonian Elders sent Sha're to him as a gift but he refused and began trying to talk to her. She was able to lead him to a cave with hieroglyphs on the wall and by reading the walls he began to learn the language and was able to learn about Ra. He also discovered the address to Earth but the seventh symbol was worn off. After the sandstorm hit the base camp, Ra arrived in his ship and had his Horus Guards attack the team members still in the Abydos pyramid. In the skirmish that followed, Lt. Porro and Lt. Reilly were killed while Lt. Louis Ferretti and Lt. Freeman were captured. When O'Neill, Jackson, Lt. Charles Kawalsky and Lt. Brown returned to the pyramid, they found Ra's ship overlooking it and armed themselves before entering. Kawalsky was captured and Brown was killed while O'Neill tried to arm a Mark III nuclear warhead that he had brought along in case of threats, but found the bomb gone. Anubis and Horus came down the transportation rings and O'Neill and Jackson were forced to surrender or die. They were taken aboard the ship where O'Neill managed to get a staff weapon and kill one of the Horus guards, but Jackson was killed and Ra was shielded by the children that follow him and O'Neill was beaten down when he hesitated to fire. After Ra resurrected Daniel in his Sarcophagus, Ra explained that he was going to send the bomb to Earth with a shipment of Naquadah to increase its destruction.
The next day, Ra forced Daniel to execute his friends publicly, but a group of young Abydonians, led by Skaara and Sha're, having learned their history from the cave walls, rebelled and created a distraction, allowing him to shoot at Ra and escape with the team, though a few Abydonians along with Freeman were killed. They returned to the caves, while in the caves Daniel finds out Sha're and him are married. He asks Sha're about this marriage and states that she hasn't told them he didn't want her, yet by now Daniel has feelings for Sha're and kisses her saying he accepts being her husband. While talking to Sha're's brother he discovers the seventh symbol. The next day, the team and the rebels infiltrated the miners and O'Neill killed Horus. Jackson exposed Horus' face to the Abydonians to show them that their gods were just regular men and then the team joined the caravan that delivers a tribute of Naquadah to Ra. Jackson, O'Neill and Sha're went inside the pyramid with a few of the rebels while Kawalsky and Ferretti along with the rest of the rebels waited outside. O'Neill was revealed and started a gunfight that left two of the three Horus guards dead and all but himself. Jackson and Sha're killed the last Horus guard closed the door and shot a blast that knocked everyone outside (charging the temple) off their feet before O'Neill killed him with a staff weapon. O'Neill discovered the bomb and armed it, but before he could do anything else, Sha're was killed by a Horus guard that Jackson then killed.
Desperate, Jackson used the opportunity when Anubis ringed down to send the bomb to Earth to ring to Ra's ship and used his sarcophagus to resurrect Sha're while O'Neill fought Anubis and tried to disarm the bomb. Ra found Jackson on the rings trying to return to the pyramid and started killing him with his Kara kesh. O'Neill managed to overpower Anubis and positioned him under the rings, activating them, decapitating Anubis. On the ship, Jackson managed to break free as the rings activated and he and Sha're escaped as Anubis' head traveled to the ship. Seeing that they won, O'Neill tried to deactivate the bomb, but was unable to as Ra rigged it. Having lost, Ra left Abydos in his ship. With less than a minute left and no way to disarm the bomb, Jackson and O'Neill came up with the idea to send the bomb to Ra's ship. They ringed the bomb on board and Ra could only watch in horror as the bomb exploded, destroying the ship and killing him. After Ra was killed, Daniel remained on Abydos with Sha're, to be with his wife.
Having lived on Abydos for one year, Daniel had no access with Earth and lived peacefully with the Abydonians. After Apophis went through Earth's Stargate, the United States government thought he came from Abydos. Colonel Jack O'Neill was able to convince Major General George S. Hammond to contact Daniel Jackson, which was successfully performed via a Kleenex box. Jackson replied back to send more, which prompted O'Neill and his team to journey to Abydos, where they were reunited with Daniel Jackson and the other Abydonians. Daniel Jackson had discovered a cartouche, which charted a vast network of Stargates across the galaxy, on Abydos, which he showed O'Neill and Captain Samantha Carter. Apophis also arrived, kidnapping Sha're and implanting her with his queen, Amaunet. Daniel was brought back to Earth and, upon his request, made a member of SG-1 with O'Neill and Carter. When he, along with SG-1 and SG-2 went to Chulak, he and his team were caught by Apophis and imprisoned. They were able to escape with help of the Jaffa Teal'c, but Daniel was unsuccessful in retrieving Sha're. Shortly after the mission on Chulak, Teal'c joined the team as well, having proved his loyalty by killing the Goa'uld inhabiting the body of Major Charles Kawalsky.
Jackson discovered that Ernest Littlefield had gone through the Stargate in 1945 and convinced Major General George S. Hammond to authorize a rescue mission. On the planet, dubbed Heliopolis, Littlefield showed Daniel a meeting hall containing information about an Alliance of Four Great Races, including a diagram that explained the mystery of life. Even though the whole structure was about collapse into the ocean, Jackson was more than a little reluctant to leave the planet.
His teammates were made to think he was dead by Nem, an Oannes, who kidnapped Daniel to discover the fate of his mate, Omoroca. Under the influence of her hypnotic breath, Daniel had sexual intercourse with Hathor in order for her to produce Goa'uld symbiotes. Though he can't have any recollection of this, having lost all his memory of what happened while he was under Hathor's control, he is rather repulsed by the knowledge.
On a mission to P3R-233, Daniel discovered the Quantum Mirror and was transported to an alternate reality where he had never joined the SGC and Earth was being annihilated by Apophis. Using information from that reality which included the gate address for the location where the invasion would be launched from, SG-1 managed to prevent the same attack in their reality, simultaneously confirming the worth of the Stargate Program despite the efforts of Senator Robert Kinsey, who considered the Program to be a huge waste of money and resources.
After Jackson saved Shyla, the daughter of Pyrus, from suicide, SG-1 was imprisoned. Shyla, however, took personal responsibility for Daniel, with whom she was infatuated. Daniel became addicted to the Goa'uld Sarcophagus and experienced severe withdrawal symptoms when brought back to Earth while also displaying Daniel's darker side as he became increasingly arrogant and selfish, even turning on his teammates. He tried to escape but eventually suffered a breakdown and was returned to the infirmary. Once he was returned to his normal state, he convinced Shyla to destroy the sarcophagus.
A year after joining SG-1, Jackson and Teal'c traveled to Abydos and discovered Sha're was pregnant with Apophis' child. After the birth, Amaunet resumed control of Sha're's body having 'retreated' during the pregnancy due to the risks of causing a miscarriage and rejoined Apophis. The child, a boy, was hidden away to prevent him from falling into Apophis' hands.
Some time after the successful mission that resulted in the death of the Goa'uld Setesh, SG-1 and SG-12 brought a Goa'uld artifact known as the Gift of the Gods to Stargate Command. The Gift created an alternate reality in which only the SGC existed, along with its personnel, amid nothing. Shortly after that, the SGC was attacked by a Jaffa strike force. The Tau'ri held the line, but Daniel was killed in the battle. Meanwhile, the SGC personnel in the alternate reality decided to avert the potentially disastrous effects of the Gift, which linked the Stargates of the two versions of the SGC in a manner that could destroy Earth in the main reality if the wormhole closed. The alternate Daniel Jackson removed the artifact from his reality, which was created only hours ago along with himself, with false memories, thus destroying that reality. He subsequently replaced his dead counterpart in the main universe.
On a planet where they were rescuing the Abydonians, Daniel again met Sha're/Amaunet, who had stolen back her child. However, when Amaunet used her Kara kesh on Daniel, Teal'c was forced to kill her. Daniel wakes up after being knocked out to discover his wife is dead. Not taking the news lightly, he views her body to make sure of it himself. A short time later he has visions from Sha're, one in the hospital, second at his home, and third at his house where Sha're died. After recovering from his wounds, Daniel resigns from his duty at Stargate SG-1 due to the fact he stayed on to find his wife and now that she is dead he has nothing left. In his final vision from Sha're she explains how he needed to find the child, whom he discovered was a Harcesis. They kiss one last time. At the end, Sha're is shot but in her final moments regains control over her body, saying, "I love you, Daniel," before dying. Daniel replies "I love you, too," while he strokes his wife's cheek. He then returned to his position with SG-1 to find the Harcesis.
Daniel Jackson finally located the boy on Kheb and discovered the Ascended, including Oma Desala, and he left the child in her care.
Daniel was reunited with his grandfather Dr. Nicholas Ballard when SG-1 discovered a Crystal skull similar to one Nick had discovered in Belize in 1971. Nick chose to remain behind on the planet with the "giant aliens" they discovered there, so he could teach and learn from them.
When the Eurondans offered Earth their technology in exchange for heavy water, which would allow them to win a world war, Daniel Jackson protested, stating that they should find out more about the war before making the Eurondans their allies. Colonel Jack O'Neill didn't agree with him until he discovered the Eurondans were nazis.
On P3X-888, Daniel made friends with an Unas known as Chaka. When Colonel Jack O'Neill wanted to destroy a ship that was killing the Enkarans, Jackson again protested, as it would have wiped out the Gadmeer, an extinct race who were being recreated by a terraforming ship they had developed. While talking with Lotan (an artificial Enkaran created by the Gadmeer ship to communicate with the population), Daniel was able to convince him to stop the ship's terraforming of the planet by arguing that the Gadmeer would not want to be restored to existence at the cost of another civilization. Scanning the ship's databanks, Lotan was able to discover the location of Enkara, providing his ship to relocate the population to that planet on Daniel's suggestion before it resumed the original terraforming project.
When David Jordan, an old mentor of Jackson, died, Daniel attended his funeral and was reunited with his some of his old colleagues, including his ex-girlfriend Sarah Gardner. However, Gardner was taken over by the Goa'uld Osiris, who escaped from Earth in a starship hidden in Egypt.
On Abydos, Daniel again met his stepson, who he discovered had been genetically aged and was named Shifu. Jackson asked the boy for the information he possessed on the Goa'uld, but Shifu said Oma Desala had taught him to forget the information. When Daniel tried to convince him to remember it anyway, Shifu gave him a vision in which Shifu gave Daniel his genetic Goa'uld knowledge. With his knowledge, Daniel unofficially took command of the Stargate Program and began designing anti-Goa'uld satellites, known as AG-3's. His personality also began to develop into a more ruthless and cruel one. When planning the construction, Daniel forbade informing the Russians or the Tok'ra of the construction, completely breaking the treaty between Russians and Americans. Jackson took a much greater interest in Goa'uld technology and wished he could use it.
One year later, the AG-3 satellites were finally ready and much had changed at Stargate Command. Colonel Jack O'Neill was apparently retired because his presence in the SGC wasn't necessary anymore and Daniel thought he was jealous. Major Samantha Carter had become a protestant against the AG-3 satellite program and believed that Jackson intended to take over the world. Something mysterious happened to Teal'c as well 1 year ago during his mission. Shifu was living with Daniel. Major General George S. Hammond was unmentioned. After another confrontation, Carter was finally arrested and pleaded that O'Neill kill him. When the long-awaited day came, Jack went to see Daniel, who took him to an underground complex which served as Jackson's main base of operations. After the success of the satellites, the Russians became angry and sent weapons to destroy the satellites. The AG-3 system easily destroyed them and the Chairman of the Joint Chiefs of Staff, General Maurice Vidrine advised to take out their launch sites. In a "wish to prevent a global nuclear war", Jackson boldly overrode the command of the satellites and took control over the AG-3 system. He cut off communication with Vidrine and targeted Moscow. Jack tried to shoot him, convinced his friend was gone, but the bullets bounced off the Goa'uld shield. Moscow was destroyed and Daniel triumphed... until the dream ended.
In the aftermath of Teal'c dying on Vorash, Daniel tried to offer Jack some comfort with Jack even going so far to speak to Daniel, demonstrating their strong friendship.
Later on while fleeing from Replicators who had claimed Cronus's ship, Daniel was seen firing at many Replicators, hinting that he had received training regarding military weapons and combat tactics. He, Jack and Sam later witnessed Apophis's ship crashing into Delmak.
About a year after first meeting him, Daniel's Unas friend Chaka was kidnapped by a civilization that used the Unas for slave labor. SG-1 freed Chaka, but Chaka chose to remain behind so that he could begin an Unas rebellion.
When Teal'c was trapped in the Stargate, Daniel was sent to Russia to help Major Paul Davis convince the Russians give the Americans their DHD so that Carter could save Teal'c.
Jackson impersonated Yu's servant Jarren at a summit of the System Lords, where he planned to release a deadly poison that would kill the System Lords. There he again met Osiris. Osiris revealed that Anubis had returned and, realizing how powerful Anubis was, Daniel didn't carry through the Tok'ra's plan to kill off all the System Lords.
Jackson again became angry with Colonel Jack O'Neill when he killed Reese to save the base from an infestation of Replicators. Always one to see the best in humankind (or android or alien-kind), Daniel believed he was very close to persuading Reese to cease the attack, but O'Neill stated he had no way of knowing that and pointed out what would have happened if just one Replicator had escaped from Cheyenne Mountain.
Daniel sacrificed himself to save the people of Kelowna from a Naquadria bomb, but the dose of radiation was lethal and he died. However, with the help of Oma Desala, he ascended. As an ascended being, Daniel found that he was not allowed to interfere in worldly matters. When Colonel Jack O'Neill was captured and tortured by Ba'al, Jackson helped in the only way he could—by offering O'Neill the opportunity to ascend himself. O'Neill rejected the offer and was eventually rescued thanks to Jackson who told Teal'c in kelno'reem how to give O'Neill a fighting chance.
Jackson later appeared to Teal'c as well when he was injured, appearing in Teal'c's delusions as a psychologist who helped him to see the reality of his delusion and return to the real world in time to be rescued. In the real world, he appeared to Teal'c again to confirm that what he was experiencing now was real and he would be okay. He also observed the capture of Bra'tac and Rya'c on Erebus but was powerless to do anything about it.
When Abydos was under a threat from Anubis, he told SG-1 and they went to the planet to help. When he discovered that Anubis was ascended himself, he decided the law against interfering no longer applied and tried to stop Anubis from destroying Abydos himself. However, Oma Desala stopped him to avoid drawing the wrath of the others and Anubis succeeded in annihilating the planet.
Returned to his physical form, Daniel was found naked on the planet Vis Uban by the Nomads of Vis Uban. He had no memory of who he was, so they dubbed him Arrom, meaning "naked one," and accepted him into their society. After two months, SG-1 discovered him and convinced him to come back to Earth, where he slowly began regaining his memory. When Jonas Quinn was soon after made the Kelownan representative for the Joint Ruling Council, he left SG-1, leaving Jackson free to rejoin the team.
With the help of Teal'c, Daniel recalled his memories of Bra'tac and Rya'c's fate, which enabled a rescue mission to be mounted, simultaneously helping Daniel feel more at peace with his return to human form after his Ascension. When SG-1 were later captured by Aris Boch, Daniel was taken as a host by the Goa'uld Sobek in an attempt to access a locked chamber on Boch's homeworld, but Sebek's control over Daniel was weakened by both the chamber- created by the Ancients to contain a knowledge-draining parasite- and Sebek's own need to kep Daniel's consciousness more active than the Goa'uld preferred in order to access the subtle nuances of Daniel's linguistic knowledge. These factors, combined with his greater age and lack of a sarcophagus, eventually forced Sebek to abandon Daniel before his death, leaving Daniel relatively unharmed from his time as a host.
While on P2A-347, Daniel's body was used by a desperate engineer called Pharrin as a host for the minds of twelve dead passengers, but Pharrin eventually agreed to remove the minds from Daniel's body in exchange for a Naquadah generator to repair the Stromos. He also vouched for the Unas living on P3X-403, using Chaka as an ambassador to negotiate an alliance between Stargate Command and the Unas to mine the Naquadah on the planet to create weapons to fight the Goa'uld.
When SG-1 were briefly trapped in the time dilation of a black hole while rescuing SG-10 using stolen anti-gravity technology, Senator Kinsey was able to arrange an alliance between Earth and the Kinahhi, providing the Kinahhi with prisoners to create an Earth-based version of a monitoring technology known as the sheh-fet, unaware that this gave the Kinahhi virtual control over the SGC. Returning to Kinahhi to rescue Jack and Sam when Kinsey had them handed over to the Kinahhi for their theft, Daniel was able to make contact with the Arxanti, another group living on the Kinahhi homeworld who possessed ties to the Ancients; the sheh-fet had been created to monitor the Kinahhi cities in the belief that they were about to be attacked by the Arxanti, but the Kinahhi had faked terrorist attacks to justify the sheh-fet's continued existence. When the Arxanti linked Daniel up to the sheh-fet, he was able to transmit his unique insight and knowledge of the Ancients into the minds of everyone currently connected to the sheh-fet, thus confirming that the Arxanti were no threat to the general population, Jack O’Neill subsequently releasing the prisoners from the sheh-fet thanks to his more powerful Ancient gene granting him superior control over the system.
While on a mission to Honduras to recover the Ancient healing device that could be used to fight Anubis' Kull warriors, Jackson and Dr. Bill Lee were captured by local guerrillas. After being rescued from the Honduran terrorists by Colonel Jack O'Neill and CIA agent Burke, Jackson and Lee were brought back to Stargate Command.
When Osiris beamed into Daniel's home and attempted to manipulate his dreams in order to locate the Lost City, SG-1 figured out what was going on and captured her. She was taken to the Tok'ra, who had her symbiote removed. Daniel told Sarah that what Osiris made her do wasn't her fault and that he would help her overcome her feelings of guilt.
When Earth's alliance with the Tok'ra and the Rebel Jaffa broke down, Daniel tried passionately to rectify it, but to no avail. On Emmett Bregman's advice, Jackson recorded a few seconds of a mission to P3X-666. Bregman was reluctant to include this footage, which depicted the death of Dr. Janet Fraiser, in his documentary, but Daniel told him that he thought it showed "what Janet Fraiser was all about."
When Anna was discovered at a secret NID laboratory, Daniel tried to help and comfort her, although the security tapes seemed to show she was guilty of murder.
After discovering the Antarctic outpost and foiling Anubis's attack on Earth, Jackson, with the help of Dr. Elizabeth Weir, negotiated a shaky agreement with the System Lords. He later determined the Gate address that would allow a team to reach the lost city of Atlantis. He pleaded with Brigadier General Jack O'Neill to allow him to join the expedition but was denied.
When SG-1's arrival on the planet Tegalus caused civil unrest by confirming the beliefs of a religious group, Daniel attempted to prevent a full-scale civil war from occurring. He failed and was trapped on the planet until he was rescued and Soren, a religious zealot that had taken over the Rand Protectorate, was killed. When Teal'c was trapped inside a virtual reality pod, Daniel entered the simulation too in order to rescue him, the system being reprogrammed so that Daniel would experience a two-second 'warning' of any danger in the system so that he could help Teal'c anticipate potential threats and beat the game.
A group working for The Trust blackmailed Daniel into giving them the translation to beam aboard the Al'kesh left behind by Osiris after framing Teal'c for murder. When this group used the beaming technology on board to steal the Stargate, Jackson discovered, from Dr. Hugh Bricksdale, how to beam aboard the ship. With the help of Lt. Colonel Samantha Carter and Teal'c, he recovered the Gate, but the Al'kesh escaped into hyperspace.
On Jack's protests and insisting that they needed Daniel here, Lt. General George S. Hammond selected Daniel to accompany an expedition on the Prometheus to locate the lost Atlantis expedition. However, the ship was hijacked by Vala Mal Doran, who was planning to sell it to two prospective buyers. She had more than a passing amorous interest in Daniel, but he considered her a "fruitcake" and was more interested in regaining control of the ship. He was ultimately successful, but Vala escaped in an Al'kesh that had recently been repaired by the rest of the Prometheus's crew. The damage sustained was such that the mission had to be discontinued.
When Robert Kinsey was captured by Goa'uld agents of The Trust and turned into a Goa'uld himself to trick the Russians into thinking the American administration had been overtaken by the Goa'uld, Jackson went to Russia and, with the help of Captain Daria Voronkova, he tried to prevent a nuclear war from occurring.
When Daniel was captured by Replicator Carter, he was tricked into revealing the location of the weapon on Dakara, which was the only weapon that could be used to destroy her and all the other Replicators. However, the weapon was still activated and the Replicators were wiped out, but Jackson was killed. The success of this was partially due to Daniel himself as he engaged Replicator Carter in a battle of wills and defeated her, taking control of the entire Replicator army and freezing them long enough for Lt. Colonel Samantha Carter and Jacob Carter to recalibrate and fire the weapon. Replicator Carter managed to regain control and killed Daniel by stabbing him through the heart with a sword composed from her own right hand which happened seconds before the weapon fired.
Oma Desala gave him the chance to ascend again, but he was reluctant when he learned that Anubis was planning to retake Dakara and use the weapon to destroy all life in the galaxy. Eventually, Oma decided to fight Anubis. She wouldn't be able to win, but neither would he and he wouldn't be able to do anything but fight her back. With the galaxy effectively rid of Anubis, Daniel ascended and immediately returned to his physical form.
Using a modified Puddle Jumper, SG-1 traveled back in time to Ancient Egypt to acquire a Zero Point Module. However, Ra's Jaffa found their ship, preventing them from returning to the future. SG-1 placed the ZPM in a tomb that would be discovered shortly before they left, so they would never have to go on the mission in the first place. However, the future was altered and alternate versions of the team, minus Daniel, who had been killed, traveled back in time to set things right. The Daniel Jackson of the "original" timeline lived out the remainder of his life in Ancient Egypt, but the "future" Jackson never went on the mission and remained part of SG-1.
Sometime after this, Daniel decided to leave SG-1 and join the Atlantis expedition. However, Vala Mal Doran came to Earth in search of a treasure. Daniel concluded that the Ancient who made the tablet was Merlin, and the treasure was hidden in Avalon. In order to ensure that she would get her "fair share," she bound herself and Jackson together with two Kor mak bracelets. However, she was unaware their powers would work both ways. Along with Lt. Colonel Cameron Mitchell and Teal'c, they did find Avalon hidden under a hill located in the England. There they found a Long-range communication device that Daniel and Vala used to place themselves in the bodies of Harrid Cicera and Sallis Cicera, two heretics living in another galaxy. Although Mitchell eventually managed to free them by throwing the device into the Unstable vortex of the Stargate, the Ori became aware of the existence of the Milky Way galaxy. Feeling responsible, Daniel decided to remain with SG-1.
During a later mission to a lab containing a laboratory that had once belonged to Anubis, SG-1 discovered a man called Khalek, who was later revealed to be the 'son' of Anubis, an evolved human possessing Anubis's genetic memory and a portion of his powers. Although Daniel argued in favor of killing Khalek, aware of the danger he could pose, the International Oversight Advisory kept him alive so that he could be studied in the hope that analysis of him would help them find a way to counter abilities like his in the field, as the Ori's Priors possessed similar powers. The research proved successful in identifying certain sound frequencies that, when broadcast, could prevent a Prior from using his abilities for a certain time, but Khalek was responsible for two deaths while he was being studied, and the SGC were only narrowly able to prevent him returning to Anubis's lab and completing his goal of Ascension.
After Daniel was accidentally shifted into an alternate dimension with Lt. Colonel Cameron Mitchell and Lt. Colonel Samantha Carter, Daniel learned of a weapon designed by Merlin to neutralize the Ori. They traveled to Camelot, where they learned that the weapon in question was the Sangraal. It was also said that King Arthur and the Knights of the Round Table left to three distant lands to search for it: Castiana, Sahal, and Vagonbrei.
Daniel was presumed killed in the Battle of P3Y-229, but actually ringed over to an Ori warship, one which was carrying Vala Mal Doran. They attempted to kidnap Adria the Orici, but when that plan failed, Daniel resolved that they had to kill her, as she was "an Ori in human form". Traveling to Atlantis, he encountered the ascended Morgan Le Fay, asking her for the addresses of the planets the Sangraal might be on. All three turned up empty.
Several months later, Daniel realized that the three planets in question formed a perfect triangle in space with in the center of that triangle a point showing a fourth planet, while Vala Mal Doran realized that the address for the planet with the Sangraal was on one composed of Castiana, Sahal, and Vagonbrei's addresses. However, they had been lead there by Adria, who needed Daniel to find the weapon. It was learned that Morgan Le Fay was not protecting the Sangraal, but Merlin, who was in stasis. However, Merlin's body had deteriorated too much during that time, and his memories were downloaded into Daniel. Daniel managed to build to phases of the Sangraal, but was soon captured by Adria, with SG-1 being forced to leave him behind.
While Adria's prisoner, Daniel was seemingly swayed to become a Prior, but he actually hoped to complete the Sangraal and send it to the Ori home galaxy, Merlin's downloaded personality protecting Daniel's mind from Adria's influence. After allowing himself to be captured by SG-1, he tried to convince them and Major General Jack O'Neill that he was still on their side, and gave SG-1 intelligence to capture the Ori warship carrying the incomplete Sangraal, but used O'Neill to hijack the Odyssey. Daniel redirected the Ori ship through the now deactivated Supergate, destroying the Ori before a "kill switch" Merlin had implanted during the original download caused Daniel's body to revert to its original state. However, more Ori warships were able to come through as a result.
Some time after this, Daniel began to have visions of what appeared to be Merlin - although it was later revealed to be Morgan Le Fay - alerting him to the existence of the Ark of Truth, a device that, when activated, would make anyone who looked into it understand that [and why] the Ori were not gods. Guided by his visions and with the help of Tomin, Daniel, Vala Mal Doran and Teal'c were able to discover the Ark, although they were subsequently captured and taken to the City of Celestis, where they learned that the now ascended Adria was the sole Ori left. Having activated the Ark, Daniel and Teal'c arranged for the Doci to look into it, his newfound disbelief in the Ori subsequently being 'transmitted' to every other Prior in the galaxy due to the link between them and their staffs. With Adria now weakened, Morgan attacked her, the two engaging in eternal battle, much like Oma Desala vs Anubis.
Over a year after the fall of the Ori, around the time Atlantis rescued Teyla Emmagan and Colonel Samantha Carter returned to the Milky Way, Daniel went with SG-1 to the Extraction Ceremony of the last Ba'al clone. Along with SG-1 and General Jack O'Neil, they watched as the last Ba'al clone was killed and the host was being helped by Vala. Daniel then returned to the SGC and wondered about what Ba'al had meant about his plan and such with Colonel Cameron Mitchell.
A couple of months later, Daniel traveled to Atlantis to carry out research on the renegade Ancient scientist Janus. With the aid of Dr. Rodney McKay Daniel discovered Janus' lab, but the two of them were captured by the Vanir - a renegade group of Asgard who had long ago split away from the rest of their people - and forced to activate a forbidden weapon created by Janus called the Attero device, which destroyed Wraith ships currently in hyperspace at the cost of simultaneously destroying every active Stargate in the Pegasus galaxy. Having discovered that the alien race were a group of Asgard who had long since cut off contact with their brothers, Daniel and McKay were able to shut down the Attero Device using the Asgard's Armored exoskeleton, although Daniel was injured in the attempt and subsequently sent back to Earth after Atlantis' Stargate - which had been destroyed when the device was activated - was replaced.
By 2009, Daniel hosted a series of videos in order to provide a crash course of the Stargate Program to those who just been cleared to know of its existence. It is unknown exactly how many videos he helped to create, but it was at least six.
After the Atlantis expedition officially negotiated a treaty with the Wraith, Daniel returned to Atlantis with the primary goal of tracking any Asgard outposts in Pegasus, as well as potentially learning more about Wraith culture (although this led to a slight misunderstanding when Wraith naming conventions prompted Atlantis's Wraith ally, Guide, to assume that Daniel's name meant that he was Jack O'Neill's son). Although there was some brief tension between Daniel and Teyla over their mission objectives, Daniel and AR-1 were able to not only find an Asgard outpost, but also make contact with Elizabeth Weir following her return from Ascension, as well as rediscovering the long-lost Aiden Ford. After learning that the Vanir were trying to make contact with Ran, an Asgard who had Ascended long ago, in the belief that her genetic material might help them solve their genetic degradation, Daniel, Elizabeth and AR-1 were able to negotiate for Ford to leave Pegasus while the Asgard used an Asgard ship to take them back to Earth, where they were able to ask for Ran's help at a shrine dedicated to her. Returning to Atlantis, Daniel began to talk with the Wraith cleverman, Ember, about the significance of the Gift of Life to Wraith culture and what the new retrovirus would mean for future human/Wraith interaction.
A short time later, Daniel tailed Dr. Nicholas Rush, who tried to infiltrate the Lucian Alliance in Colonel David Telford's body. Unfortunately, Rush' cover was blown and he was unable to call in the strike team before Commander Kiva and her team could board a Tel'tak. Later, he briefed Colonel Everett Young and Lt. General Jack O'Neill on Kiva. He objected to Young's intention to force Telford to talk by any means necessary.
