I just think monsters are Neat! (he/him)
I thought it was Myth Drannor! It didn't make sense for the phaerimm to be there, so I second guessed myself.I think that is the first sign of the Pharenim in all of 5e history...and for some reason they are flying around Myth Drannor???
Also, there's a reference to phaerimm in a 5e adventure: Icewind Dale: Rime of the Frostmaiden.
