Now some of these gods have huge numbers of worshipers. Oslira has some two hundred thousand worshipers in Peloria. Issaries has even more, but scattered all around the world.
Argan Argar is the second most worshiped troll god, although most of his worshipers are trollkin.
What are the real world god names being used in Glorantha? Styx, Pole Star (Polaris), and Hippoi are the main ones.
