Awesome little module! It can be run pretty quickly, but it depends on the type of players you have. I ran it for two people, and they finished in a little over two hours, but they also didn't kill the goblin or rescue everyone. They rescued one NPC, and soon after, a player died, so the surviving PC just got the hell out with the one NPC they did find. I enjoyed running it, and they seemed to enjoy playing in it, though, so it was worth it! I probably should have attacked with the goblin more to drag it on a bit and made it harder for them to escape, but I'll probably get a chance to run it for another group at a later time and make those changes.
