Namira is the Daedric Prince of Decay, Shadow and Repulsive Creatures. She is thought to be associated with beggars as they live in squalor and decay. Namira's followers are know to be cannibalistic and in Skyrim the Dragonborn became Namira's Champion and she bestowed upon him Namira's Ring to allow him to feast on people as her followers do.
