Well,
Groin, I'm sure in the original Legendarium they did, being evil, but after they became a good race, who knows.
They probably did dthough, because everyone likes a bit of gold in the end (or a the very least some sort of metal) and the dwarves were all tooo happy to sell it (except for the gold)
seems like I'm contradicting myself
. Anyway, what would they want from the Easterlings?
