The God-Eaters
From The Fifth City Wiki
A trio of Third City priest-kings, made up of the the Cat, the Red Bird, and the Serpent. After bartering their Mesoamerican city to the Bazaar in exchange for the flesh of a god, they grew monstrous, gaining immortality.

The Cat, known to some as the Mottled Man, his sharp teeth, his skin mottled like the fur of a jungle cat.
The Red Bird, with her feathers of cinnabar.
The Serpent, with hands like snakes.
For the record, the unfortunate “god” devoured by the priest-kings was Mr. Candles (now Mr. Eaten), a former Master of the Bazaar. The incident has left the traces that remain of him quite cross. Very cross.
Original by NiteBrite/Mrs. Brite. The lore, however, came from the Mr. Eaten storyline.
