Inti is the Incan god of the sun. It was believed that he was the source of warmth and protection of the people. Inca Emperors also believed that they were direct descendants from him.
In Incan mythology, Sun God Inti's son is Manco Cápac (which has a card version, "Earthbound Immortal Ccapac Apu"), the 1st king of Cuzco. Sun God Inti had a wife, Moon Goddess Mama Quilla (which has a card version, "Moon Dragon Quilla").
