In Aztec mythology, Chantico ("she who dwells in the house") was the goddess of fires in the family hearth and volcanoes.
Appearance
Chantico wears a crown of poisonous cactus spikes, and takes the form of a red serpent.
Myth
Chantico broke a fast by eating paprika with roasted fish, and was turned into a dog by Tonacatecuhtli as punishment because paprika is a banned food in such fast breaking customs.
Powers
Chantico is the goddess of precious things and is very defensive of her possessions. There are many Aztec legends as to what she does to people (or other gods) who take her things.
