I picked this book up today and read all the way through chapter 1. I'm a Runewars Miniatures Game player and have been playing in Terrinoth since 2011, after picking up Rune Age and the Runewars. So I have no intention of playing the game, but I really wanted to read more about the lore in this game -- and it did not disappoint! There are some really neat things that expand on the lore I've been piecing together over time. It was such a joy to read!
One issue, though: so many typos!! It's such a shame that it was pushed out so fast or nobody proof-read it enough to get those typos out.
Still, I wish every person who said Terrinoth was a bland setting would read chapter 1 of this book. It's good!
