Fairy Knight Gawain

Fairy Knight Tristan *Her true nature is that of a girl who is kinder and purer than anyone else, unable to leave those who are hurt alone. In her past reincarnations, her goodness was exploited by the fairies, and she was killed in gruesome ways time and again. Her current persona as a wicked woman is a tragic role she forces herself to play out of the fear that she will die immediately if she isn't heartless, and a desperate desire not to disappoint her beloved mother (Morgan).*

In "Avalon le Fae," Oberon appears as a guide for the protagonist's party, a young man calling himself the "Fairy King of Britain." He is well-versed in the affairs of fairies and clans across the land, acting as a collaborator who supports Castoria and Chaldea from the shadows by providing destinations and information. He lightens the mood with his aloof personality and lighthearted way of speaking, acting as a source of emotional support for the group due to his friendly demeanor toward everyone. *On the other hand, he also acts as a strategist moving the entire story from behind the scenes, observing situations from a step back and sometimes intentionally withholding or guiding information. His true identity and goals are hidden until the end; while he is a companion on the journey, he is also a key person carrying the story's greatest mystery at its center.*
