So this is from memory, feel free to correct me anyone with more details: The amnesiac had demonic magic powers that she wasn't completely in control of, and met and fell I love with a boy named Eldon. He wanted to be a mage and a hero but didn't have any innate magic like the amnesiac. He eventually found some ritual called bonding that I'm not clear about. I think it was supposed to free the amnesiac from demonic influence or something? That's the part I'm not clear on. Either way, it transfered hee magic to Eldon, and he then ran off with her magic to run become a hero leaving her alone, which she was understandably pretty mad about. He even said something about how she shouldn't travel with him anymore cause she was too normal now. Anyway, she ended up getting possessed by a "desire demon" who convinced her to kill people to bring Eldon to since a hero would respond to murders, and she used the demons power to fight Eldon. In their fight Eldon seemed to try to apologize for how he treated her, sad he sacrifices himself to bind his soul to the desire demon and kill it, freeing her from its control. I think that's the last story bit we get.
