So there are elf nations, a ghoul nation, a troll kingdom, I think there is an ork nation (Hawaii?). But no dwarf nation?
I guess the halfers might blend too well into human society to have to worry about too much strong racism. But you'd think that some dwarf somewhere would have gone and carved up a mountain in to a city just to play up the stereotype, followed by it turning in to a dwarf version of Disneyland acting as a glorious underground tourist trap.
