Ralios is a syncretic mash-up of “Barbarian Old Gods”, Lightbringer cults, and Hrestolism, along with the some troll and elf cults. Arkat’s Dark Empire unified this land for several centuries, but has been gone for nearly a thousand years. It is a mess of rival city-states, strange religious movements, and secret societies.
Now an aggressively dynasty of warrior-kings threatens to conquer Safelster with the aid of intolerantly humanist wizards and tribes of warriors. For me, this is another fantastic Gloranthan setting. It is a different set of stories than Dragon Pass, perhaps even more strongly sword and sorcery in flavour, somewhere I could imagine Conan, Gorgik, or Fafhrd and the Grey Mouser hanging out.
