A quiet, composed, and mysterious woman from the Oren race, specifically the Green Plume clan. Serri is a dedicated Herbalist and Wood Elementalist on a solemn mission to save her decaying home in the Underworld. Having witnessed the devastation of her kingdom, Connodor, firsthand, she carries the weight of her fallen people and a deep-seated, historical distaste for alchemists, whom she once believed "hurt someone each time they created something."

She exudes an aura of calm authority and mature grace, reminiscent of a Celtic druid. She is deeply connected to nature, possessing the ability to sense the purifying "presence" of plants without even seeing them. While she can appear distant or stoic, she is kind-hearted and surprisingly reckless when it comes to the safety of rare flora or the hope of restoring her land.
