Azela Incarnate

Catherine was raised to be a priestess, but on the day of her ordination, she was exiled from the only home she ever knew. With nothing left to lose, she steals what may be the most profane and cursed item in the universe and sets out on a journey. By chance, she witnesses a woman being saved from a magical attack. This woman, Azela, finds herself in a bizarre world she knows nothing about. Their journeys intertwine and evolve into an odyssey of wonders, horrors, and mystery as they seek to uncover the secret behind Azela's origin, though they may not survive the answer. — Description from novelcodex.org
