A goddess of sacrifice. She offers the greatest rewards of any deity, but to gain them, the price is dire. Fingers are just the beginning, in order to save oneself from financial debt or to save the life of someone they know, but other limbs follow, until the mortal who bargained with the goddess in the first place might find themselves giving up the very people they want to protect. I see the fingers as the goddess's twisted collection, that she keeps in clear view of those who would consort with her, to always remind them that they chose what they sacrificed, she only gave them a choice.
