There is at least one 'tribe' of cat-centaurs known on Dragaera. It is assumed that the group that Vlad Taltos and Morrolan encounter during Taltos are the same as those mentioned to Zerika the Fourth before her journey to the Greymist Valley and the Paths of the Dead.
This group lives in the area roughly described as the Forever Plains near or at least on the normal route to Deathgate Falls.
Cat-centaurs are apparently hunters, use spears, and move at an incredible speed on foot. They honor the goddess Kelchor.
