The thief directs you in locking the passage.
To Keldar, he responds, "Well, aye. Of course we might meet them." A look of fear flickers in his eyes before he continues. "But these passageways, they're endless. There's no telling where they are, and even if they wanted to, I'm not sure they could find us in here themselves."
OOC: The unseen servant is shapeless, so I'm not sure how the cloak would lay on him. He could certainly carry a quarterstaff and trigger wire and proximity traps, and also test for (weak, <20lbs pressure to trigger) pit traps.
I still need a final destination. Temples or surface? Or somewhere else?
As you traverse the halls, you pass through all kinds of environments. First rough tunnels hollowed through rock, now a brick corridor, here a tiny crawl space, tall enough for Fimble but everyone else must crouch. A wooden boardwalk traverses a cavernous space, the sound of water dripping echoes up from the darkness below.
At one point, in an otherwise unremarkable wooden passage, you encounter a metal wire dangling from the ceiling. At the end of the wire is a handle grip. No effort has been made to conceal the pull cord, it's right in the middle of the hall way. Your unseen guide has not triggered any traps, and the meaning of this cord is a mystery to your detailed book and even to the maimed thief.
