Archaeology?

So I've got it at 525 and I'm solving stuff. Trying to figure out if I need to go to other continents? I noticed that dwarf doesn't pop up on the eastern realm much anymore. Do I have to go through all the different races to get the Tol'Vir stuff? My goal is to get the ultramarine mount.

Tol'vir is only from uldum. So you need to be in Kalimdor, not e. kingdoms.

Thanks for the help hannibal. I guess I'll be spending a lot of time in Uldum.
