This is by far the best organized reference work produced by Wizards recently that isn't a bestiary. It builds very nicely on top of the Forgotten Realms novels. The maps are great. The creatures are scary enough mechanically without being a pain. The characters are compelling.
Auril's stat block is underpowered for lvl 9+. but if you give her lair actions in the city like she has at home she'll do just fine.
That's pretty much the biggest problem in the book. 4.9/5
