Continuing deeper into the caves surrounding the underground river the party descended an underground waterfall into deeper caves. Moving away from the river the party found a section of the cave that had been clearly been worked and had a large stone door installed. After several stealth checks, and lengthy discussion, Romulox kicked in the door, finding an underground storehouse and surprising a dozen workers moving crates into the room. The party attacked and made quick work of the workers but also had to face a Shadar-Kai monk and wizard who gave them significantly more challenge. The party triumphed and searching the crates discovered human made weapons of poor quality destined for some unknown source, as well as a note on the body of the monk written in Deadspeak, the language of the dark other world, the Shadowfell. The party also found some silver and a +1 wand on the body of the wizard. They continued on into the cave system behind the storeroom.
