I think Hummaz refers to the fey of which Mostin spoke early in the update, as he specifically uses the word wild, and that makes more sense to me since the question is about Nehael's interaction with it and ability to placate it. Also, Nehael says he hasn't shown himself yet, while she has already met the Adversary.
And I'm sure they giggled like schoolgirls when they got to roll damage.**Epic conjuration/400d20 bludgeoning damage! Yay!
