Years ago, Jedas Sefit found Myiri wandering alone within the Twisted Root with no memory of her past or how she had come to be there. The hero brought her back to the surface to live in Ete, where she has remained ever since.

Myiri looks up to Fino like a brother, following him everwhere and sharing in all of his pranks and misadventures. This can sometimes take the form of overdependency; once Fino is old enough to begin exploring the Twisted Root, Myiri pushes herself to master the use of magical cards solely to avoid being left behind.

Although the group occasionally expresses curiosity about her forgotten past and wonders if the truth may lie within the labyrinth, for the most part, Myiri seems content to share in Fino's dream of discovering the greatest treasures to be found.
