I thought that the Avatar of Reathos and the Pronobi were dead and gone at some point after their creator died, what with the Wraith Stone being moved and everything. Granted I think there are some dwarves in the general area of the mountain the Stone is kept now, but Farxus hasn't really talked with them personally yet. 

Either way, I think Farxus smells enough like their old master to not be bothered. 

And you are correct in that I was inspired by Terry Pratchett.
