Tribe of people that worship the Sun. One man is seeking to redeem them to the rest of the world because in the ancient lore, their hero and champion stole the goddess from her perch above the world and they eloped together, but this ruined magic for the rest of the world and the Sun tribe fell out of favor, had their capital city destroyed and now survive purely out of the mercy of the other five civilizations, but not as a recognized entity. Mostly they live on the Moon Empire's continent since their bond was stronger than with the other four. Otherwise they take up a nomadic existence or keep very very small settlements.

Unlike the other five; the Sun tribe still celebrates their hero mightily, even if it's with a great deal of shame and everyone wears hair accessories and clothing patterned after and in the same colors of their hero.

My guy has stolen the last relic the hero left before he vanished with the Goddess and is more or less attempting to become an equally great hero to restore their honor and let them be noticed again.
