Mictlancihuatl

Mictēcacihuātl (, meaning "Lady of the Dead"), in Aztec mythology, is a death deity and consort of Mictlāntēcutli, god of the dead and ruler of Mictlān, the lowest level of the underworld.

Her role is to watch over the bones of the dead and preside over the ancient festivals of the dead. These festivals evolved from Aztec traditions into the modern Day of the Dead after synthesis with Spanish traditions. She now presides over the contemporary festival as well. In this respect, the pseudo-Catholic cult of Santa Muerte owes something to Mictēcacihuātl.
