Krypta is the Goddess of Death. Her followers are Priest(esse)s. She is allied with Fervus and opposed to Agrela and Dauros.
Praying at her temple can give heroes Wither, Animate Bones and Re-animation. It also allows heroes to resurrect dead followers, against a higher cost (of 200 per each) then at a Temple to Agrela.
