More backstory about the House and what happened with Mira! Also we meet the Cult of Valgavoth and that bad feeling I had about Winter finally pays off. Tyvar's turning out to be the MVP with how useful his transmutation magic is.
I do wonder how many main story episodes are left, given that the group is still split up and we have no idea where they actually need to go to escape the House or possibly defeat Valgavoth.
