Kallista is a Tiefling with lavender skin and large, ram like horns that are naturally overgrown with living moss and small white flowers. Her eyes are a deep, forest green with no visible pupils. She wears simple hide armor reinforced with dark wood and carries a staff made from a lightning struck rowan branch.

Kallista is exceptionally soft spoken, often pausing for several seconds before speaking to ensure her words are necessary. She finds the bustle of cities overwhelming and physically painful, preferring the slow, rhythmic breathing of a forest. She treats all living plants as if they were kin.

Born in the slums of a city that saw her bloodline as a curse, Kallista spent her youth hiding in the shadows of the harbor. When a local magistrate ordered the 'cleansing' of the tiefling district with fire, Kallista fled into the nearby ancient woods. There, she discovered that the very fire that destroyed her home was a natural part of the cycle, allowing the forest to rejuvenate. She spent the next decade in total isolation, learning the secrets of the trees and the spirits that dwell within the bark. She emerged from her hermitage only when she felt the balance of the wild was being threatened by an unnatural rot. She now walks the world to ensure that the flame of life is never extinguished, and that the decay of civilization does not choke the roots of the earth.
