Dzemael Darkhold being a cave doesn't mean anything in terms of Duskwight/Wildwood; it's basically a cave that was in a convenient spot to build a fort, not an ancestral home on the same level as Gelmora the the Shroud. I feel fairly certain that at least the 4 noble houses are already all confirmed to be Wildwood, though not 100%. It's not really on topic though.
