Not much role-playing here. The majority of the adventure is simply traveling through the mountains to your goal, but some interesting locations for battles keeps things interesting.
The premise is a little convoluted, but the adventure runs really well. Especially liked encounters that were not strictly fights to the death. Some opportunity for roleplay and moral dilemma.
The adventure does seem very deadly though, especially for 1st level characters. One NPC near the end could easily wipe out an entire party and the final encounter is very deadly to low level characters.
