The dwarf county was pretty neutral before Cray arrived, and therefore didn't have much in terms of warfare and fighting. They were artisans and craftsmen.
The statues plaque is written with (fake) Latin characters and apparently says "Yusha GILDIAS KURAISTON"
So it doesn't seem to be a rewrite of either Craystone or Claystone, his last name is actually supposed to be Kuraiston.. (It probably means something for Lizardragonmen)
