New to the world.. not running it, but looking to understand the guilds and the chance for some variation to what is written as fairly firm.. from what I've seen.

I'm trying to find open and active cults or priests of Odin in this world.

Also need to create future PCs or NPCs with special skills.. aka a ninja as a monk/assassin... so where would that be in this world? Is there an "Asian" flavor someplace in here? How about more pure Norse?

The Engale in Gal Land are the closest race to what would be considered Norse. In the Northern Kingdoms of Ursal, their descendants do worship All Father (Odin), Loki (Narrheit), Thor (Corthain), and others.

The Nia are the closest approximation to what might be considered "Asian", though I might be wrong about this.
