Dwarf High King for so many reasons;
1. No-nonsense-I know where I stand
2. Best beer ever invented and copious amounts on tap
3. Best facial hair ever!
4. Nicest places to live, (ooh look the elves have trees, sod that I have an under-floor heated room)
5. Newest inventions-need to get around, find Makaisson and fly air "Spirit of Grungni"
6. Most badass weaponry- "That's a really lovely looking bow you have there", "Bosh, eat my hammer"
7. Ard as nails- Not much can take you out in CC
8. Everyone loves a good grumble and the dwarfs do it best.
As always, just my opinion but it's a no brainer if you ask me
