Othinus's History
As a legendary figure and creator of worlds
An unknown number of years and phase shifts ago, Othinus, though she may have had a different name back then, became a Magic God. To do this, she went to Denmark, to the lake where Egeskov Castle will one day stand, and sacrificed her right eye and threw it into the lake as part of an enormous ritual, allowing her to obtain the body of a magic god.[11] And thus, many tales from many cultures told about her power, though some would make her seem like an old man or a vicious god of war,[7] there were implications that she herself would deliberately take forms that would now be recorded in mythology.[7][12] Othinus later used her power to change the world through shifting its phases. However, she later yearned for her original world, and despite the fact that she could have used the Imagine Breaker to change the world back, her hesitations prevented her from doing so. For there was hope that she could make the world into her original world as she saw in her mind. Moreover, there was a hope for her that she could just bring the world into a new form through phase-shifting and just settle there. Regardless, she suffered for it, and for countless phase shifts she was worn down by the suffering that she felt in each of them, something she would later visit upon Touma. Due to being worn down and the impermanence of the world, she began looking for something that would not change.[13] Specifically, she was looking for someone who can understand her, the only one seemingly constant in the world. Though she didn't know what she wanted herself—that changing the world was but a means to an end. In the end, she settled in the current world, and somehow relinquished her title as Magic God.[7]
During Thor and Touma's battle at the end of the Ichihanaran Festival Arc, Thor mentions Othinus taking extreme measures to gain knowledge such as pulling out one of her eyes, and hanging herself on a tree.[14] This refers to the steps Othinus took to become a Magic God, likely referring to the time before she relinquished being a magic god after settling with the current world as he mentions Othinus sacrificing her eye. The other is a reference to Odin hanging himself on the world tree Yggdrasil for nine days and nights, in order to learn the wisdom that would give him power in the nine worlds.
Return as a Magic God
Her unease later returned, however, taking back her title as a Magic God, earning the anger of Ollerus, forming an adversarial relationship with the man.[7] In fact, Ollerus would continuously claim that Othinus stole becoming a Magic God from him. This relationship between them extends with his magic. The first implication of Othinus' existence in the series is when Ollerus uses the queer magic, Hliðskjálf, upon Sogiita Gunha.[15] This magic, of course, is named after the high seat of Odin, which allows him to see into all realms. In the Gesta Danorum, Odin was exiled and Ollerus was chosen to take his place. This can be presumed why Ollerus currently has the Hliðskjálf.
World War III would later spurn her into action even further, as she forms GREMLIN for the purpose of constructing the Lance of Gungnir.
As Othinus is a Magic God in spite of her limitations, she is one of the most powerful beings in the Toaru Majutsu no Index storyline, and as demonstrated later, is able to reshape the world according to her will using the Lance of Gungnir.
