A lot of people worldbuild when they daydream and have the bones of a story kicking around in their brain, but have to pay the bills and raise the kids etc so they never flesh it out and write it down. What’s your story’s premise? Fantasy, sci-fi, alternate history, mystery, western, whatever genre.
Shit. No other dwarven cities? No war of reprisal a la War of Dwarves and Orcs?
I played a fantasy game (on Nintendo 64!) that had a lore waaaay too ridiculously deep for itself, but part of it was that a vaguely dwarvish race had dwindled to a single city via repeated wars and pogroms from other races, and were living under the protection of one of the large human kingdoms at the time. These dwarves were also secretly harboring the last known dragon in the world, who had given magic to humans about a thousand years ago.
There are, but they’re quite some distance away, and the story doesn’t focus on the region as a whole.
