In Chapter Fourteen of Scythian Dawn, Arixa begins conversing with a purple lizard-man named Rivann’ivoth. He’s a Senek (plural Senekeen), one of the five Greater Races of the Dawniverse. While the Senekeen have a nominal central authority, in reality their culture is feudal and fragmented. Senekeen barons, dukes, and other nobility amass their own followings and view one another as rivals rather than allies.
We’ll meet more Senekeen in Books 2 & 3 of the series.
