Inspired by Maya mythology, the deck comes in two variations differentiated by color scheme, named The Sun Deck and The Moon Deck:

The Mayans were ardent astronomers. They believed that celestial bodies were gods and interpreted their movements as gods traveling among Earth, the underworld, and other celestial destinations. Since these gods were greatly involved in human affairs (to the point that many events were planned according to certain celestial moments; dynasties often claimed to have descended from the sun or the moon), the Mayans heavily studied every aspect of the sky, especially the sun and the moon.
