There are seven hominoid races on Atys.
Races are important because they provide specific attributes that influence the homin's behavior.

Four of them have created civilizations that reflect their vision and lived experience of the world. The topic, rich in information, is covered in their dedicated portal:

Fyros,

Matis, Tryker, Zoraï.

There was a fourth primitive race, the Momos, but it has completely disappeared.
