Even without the Storm King’s Thunder storyline, the Yakfolk village might be of some interest, especially when the players are pressed to deal with the Yakfolk as well.

With my revisions, House Xorlarrin will move into Ironslag once the Fire Giants were driven away. The few remaining Fire Giants become enslaved by House Xorlarrin by its Matron Mother.

Which gets me thinking of Illithoids.

I'm thinking that, House Xorlarrin might have an expert enchantment and enslavement abilities to get the Fire Giants around their fingers, or they might have Mind Flayers in their house, or they might have an Illithoid. I don't know yet.

I do know that I'll be reworking Ironslag for this purpose.
