Mithros takes the appearance of a black man in gold armor, holding a spear with a white-hot tip.
Temples dedicated to Mithros could be found throughout the Eastern Lands. He was also worshiped in Carthak, and his temple in Carthak City was said to be quite beautiful. Two common features of Mithros's temples were polished sun-disks and candles, torches, or lamps to represent light. Mithran priests wore orange or yellow robes. In the fifth century HE Mithran priests taught the pages at the Tortallan royal palace in "thinking arts" like reading, writing, and mathematics. The Mithran cloisters at the City of the Gods trained mages. Advanced studies included theology as well as magic- students became either priests of Mithros or priest-mages. A Mithran black and gold robe indicated mastery. Mithros's clergy was exclusively male. Not only was he worshiped in Carthak, but also in the Copper Isles, brought over by luarin, or white, nobles who took over the isles in the 100 HE. He and his sister the Great Mother Goddess, helped the luarin to take over the raka, or native people's islands, by banishing their brother Kyprioth, the islands' patron God, to the ocean around it.
Marriages before Mithros involve the couple lighting a fire together and exchanging necklaces of marigolds. A priest of Mithros, along with a priestess of the Goddess, preforms royal marriages in Tortall.
On Midwinter, mummers may dress as animals and ask Mithros to bring back the sun.
Mithros's name comes from the ancient Persian god Mithras.
