I ran this in context of a post-Tomb Of Annihilation home game, with a couple of minor changes to fit our ongoing stoyline.

This is a good module for roleplay, with colorful NPCs and a player character who gets infected with strange visions. Lots of potential for collaborative storytelling if that's your thing. There isn't much in the way of exploration (other than a secondary mystery if you count that) in the fairly linear story. You get some decent combats, with a challenging "boss," but I'm not a fan of the way the latter can use banishment to potentially take two characters completely out of the fight.

As fun as the roleplay can be, the adventure progression does feel a little forced; "I have information you need if you do me the favor of killing this monster" feels a little trite. However, it does feed the tier 3 post-Tomb of Annihilation storyline (which isn't as cohesive as the tier 4 one), it's still a lot of fun, and the prep isn't too demanding.
