I recently got the chance to play Lowhhrick and loved it, and am now running the game for a different group of players. In doing so, I felt the bartender kinda railroaded the adventure, so changed his read aloud text slightly and expanded Mos Shuuta so there was more to do and see there.
I've been posting the details of my expansion over at DailyEncounter.net
