Forest Ranger in Gandharva Ville (Sumeru region). As a sickly child in Sumeru, she suffered from a fatal disease called Eleazar and was handed over to the Fatui (specifically the Harbinger Dottore) by a corrupt priest. She was subjected to brutal human experiments involving "Archon Residue" (god remains), leaving her with deep physical and psychological scars. She later returned to Sumeru under the care of the General Mahamatra Cyno and the Forest Watcher Tighnari. Fully cured of her illness and free from the burden of the divine remains, she turned her life around to become a dedicated and warm-hearted Forest Ranger.
