The Danger Gang Auxiliary Polishes Off This Shadow Realm Dungeon

The Danger Gang Auxiliary wake up from their nap and prepare to leave the Secure Shelter when Wirshin's Detect Traps detects a trap on the door of the shelter. He sticks his head out the window and spies a couple of leeches on a little platform above the door. Arben dumps some salt on them and they move on with their lives.

They head back to the room with the rich stuff, which they had previously aired out using a Stone Shape. Inside they find a ton of money, two potions, and a deranged looking martyr. "For the Snake Gods" he yells, then tries to light himself with a flint and steel. He doesn't take, though, and Wirshin rapidly Dispels the ensorcelment he's been suffering from. He says his name is Anton and he's part of the party Costicu sent in. He's a ranger. They take him and the bars of precious metals back to the Secure Shelter. Arben gives Mirella the old gypsy high-sign that she can feel free to steal whatever she can carry from this pile of treasure.

The Gang continues through the dungeon. They leap over the pit of the Crimson Mist and press on. There's a hallway with a shaft leading upward. At the top of the shaft is another hallway with a Phantom Troll. At the end of the hallway is an archer, presumably the last member of Costicu's doomed suckers. They turn the troll and Dispell the archer's ensorcelment. His name is Marko, he's a thief by trade. He thanks him and they thank him and everybody is happy.

There's one room left for them to explore. In the room there's burn marks all over the walls and a skull with a red gemstone in one eye. There's also a small pack. The gem doesn't detect as magical, but something in the bag does. Inside the bag there's a pouch with a drawstring, a mirror, some writing implements, and the following note:

"Another fake. Hakim, this is stupid. We could spend years digging in every crappy dungeon in the TK. I say we just take the shortcut. After all, who's to know? We won't even be the ones wearing it."

Suddenly it's all so clear! Of course. The answer has been staring them in the face this whole time. Now, if they only knew what that answer was.
