Yerin

Yerin's History

Yerin was known to be a genius in her hometown before everyone was slaughtered by her Blood Shadow. Afterward, she held it down and stopped it from attempting to kill the Sage of the Endless Sword. Although he was completely safe, he was impressed by her willpower and natural talent, and chose to take her on as his apprentice, which caused the sages marriage plans to be thrown off. He challenged her and caused her many injuries and scars, taking her around the continent for training. Near the end of his life, he took her to Sacred Valley to keep her safe from the wider world. After his assassination at the hands of the Heaven's Glory sect, she was driven out of the temple they were using as a base. She met Wei Shi Lindon, avenged her master, and used his Remnant to ascend from Jade to Lowgold, allowing her to leave with Lindon on their journey.

Yerin despises her Blood Shadow, and avoided using it for as long as possible, though she grows to work with it at the encouragement of Eithan. She learns to cooperate with it as it develops its own sentience and identity. This happens for the first time in Underlord, when Yerin is at death's door as a result of Meira Riyusai's lifeline-destroying attacks. This experience helps her find her Underlord revelation, required for advancement, that she practices sacred arts is so she never has to go through the pain of losing someone important to her ever again. The two eventually fuse into one being, a pseudo-Herald, to win the Uncrowned King Tournament, a worldwide tournament of the greatest young Lords, meant to decide the path of the world's future.
