Excellent and gameable. It will be a great tool when my characters tread the frozen north. Can't wait for volume 2!

Excellent adventure! I ran it using Whitehack, and my players had a blast. This was an encounter on the way to Hot Springs Island, and the party acquired a pirate henchman, as well as some unique loot. It took 2 four-hour sessions, but they (I think wisely) elected to not risk the deepest level.
