Warriv is just rolling along in his caravan through swarms of Fallen, goat men, Bigfoot guys, and eventually cat people and electric beetles, between the Rogue Encampment and Lut Golein. He has to be one scary dude to pull
that off.
That's my line of thinking as well.
He's the only one who moves around and works. The rest just park their lazy asses and "trade".
