The Camazotz were werebats, Gaia's nocturnal and southern hemisphere messengers, counterparts to the Corax. They were almost wiped out during the War of Rage, but none survive today: the few who lived on in South America were destroyed by the Shadow Lords who arrived with the Spanish in the 1600s, and their fall saw their creation rites stop working, rendering the Camazotz of Australia the last of their kind.
The Xibalan were those werebats dedicated to the wyrmish aspect of their patron. They vanished when the last Camazotz died; however, it's hinted some are held in stasis and ready to serve the Wyrm again.
Bloodbats can be related to their Kinfolk, and via them their dark legacy continues.
