Oh, brother!
Tenebrous keeps looking about him, not wanting to be ambushed. He thinks that doors at the end of long hallways are especially dangerous for the traps that accompany them.
Oh, brother!
The Monk listens intently at the door, but hears nothing. The door is a rather large and heavy door as it's mostly made of stone, very similar to the secret door the party just came through. He searches for traps, but none are found. There is a large iron handle running vertically along the side that presumably opens. There are two iron supports for the handle and the supports are sunk deep into the stone door; again, very similar to the secret door. The door is not locked, nor does it seem to have a locking mechanism, at least on the side you're inspecting.
I just KNEW someone would make this joke - as soon as I saw he named his Monk "Jim" - but I honestly expected it from Steve's Cleric!
The Monk pulls on the large metal handle. The the door is extremely heavy, but glides on its hinges easier than expected.
