When I first started playing RQ our parties consisted of Dwarves, Elves, trolls and everything in between. This can still happen easily if folk want. Who cares if someone says they cant. Glorantha can be a totally unnecessary pain in the arse sometimes.
Elves who leave their forests are probably insane, Dwarves who leave their homes outcasts and Uz probably just hungry. Sounds like a great bunch of adventurers to me, especially if it's a Baboon shaman keeping them all in line.
There's far more bizarre stuff walking their world...
