Atana Costel (pronounced ah-TAH-nah cost-ELL) is a cleric of Taliash who resides in the Erenite village of Dalyan. Costel was born and grew up in western Thadria, in a small community on the coast of the Bay of Ertan, but moved east to Erenon several decades ago with the first wave of colonists resettling the province. She now serves as the spiritual guide to the small community in Dalyan.
Costel has a dislike for both the rule of Sircathe Wriys in Wymoor and for the current Viridian efforts to reclaim the province of Erenon. She keeps these opinions private, however, preferring to focus on aiding the villagers of Dalyan.
