After the initial fight, the trial scene and further onwards is just denouement from the last two books. But it feels well deserved--while the action isn't as intense as those two, it is something of a lull period. Shan divides his 12 books in this series into individual trilogies, and this really does feel like a conclusion to a saga that we've been invested in for that whole time so a bit of a "breather" in this book is not the worst thing in the world. It's very chill.
