Scrod leads you through the north door down a small hallway. There is a single door, to the right. He points to it and says, "That's the armory, it's locked, those who need access have the keys."
"We're going this way" he says, pushing open a hidden door on the west wall.
This area is the north end of a large natural cavern, but it has been finished with dressed stone block walls and a flagstone floor. Several barrels are stored against the walls here, along with a number of empty crates, straw for packing, hammers, pry bars, and nails.
The cavern continues for some distance to the south. You can make out several passages that open up off the larger cavern, and what looks like a deep pit or crevasse in the floor.
"I'm gonna go check in with some of the other guys, I'll be back", Scrod says turning to leave.
