A nice side trek adventure with an interesting story. The author even includes optional ending ideas - one being that this could be an entry point to the Underdark. I particularly like the layout, cartography, and the sidebars that describe the D&D rules. These are great and it's nice not to have to refer back to the PHB or DMG during the game! I'm looking forward to more work by Glen Cooper!
