Well, ye’ve found the place alright…
Umbria is a large island continent situated in the northern hemisphere of the planet. The inhabited landmass is about 3 million square miles, though there is a frozen wasteland of unknown size that extends up north of the large mountain ranges.
It is mostly populated by the human Nords, though there is also fair representation of elfs, dwarfs, gnomes, and the monstrous humanoid races. Of note, there are no native halfling populations on Umbria, so these folk in particular are viewed with suspicion, or just assumed to be gnomes.
