Get it because it's free, but it's the weakest book of AoS. IMHO. I'm up to book 6 in the RGW, and I like the Hallowed Knights story arc, so that's the Stormhost I've gone for.
There have been mentions of scattered bands of humans, but barely savages,
There hasn't been much mention of what it's like to live in cities, to be rich or poor, what it's like to grow food, festivals, a days work, have families, what a pub in Azyrheim is like.
