"That seems a strange and difficult to reach place to hide a trap. I'd be inclined to see what you can do with it. You are welcome to one of my crossbow bolts of that would help. I think with the arrowhead removed it might allow you to do more than simply push the stud."
Sorry - I posted that Deasaigh offered up one of the black arrows found after the fight with the Mantis Men rather than one of his own, but got kicked offline before the post could go through.
As he pokes and prods with the crossbow bolt, Skáth feels the metal stud at the back give a bit. A low rumbling preceeds movement as the back wall of the room receeds about three and a half feet, revealing a set of stairs leading down and to the north.
"I can't but wonder how is this a practical lever. Only a giant, even larger than ours," looking at Bear, "would be able to reach that hole. I don't want to meet him along our journey. That all said, let's continue down the stairs."
Gavril gets the lantern and responds to Skathe. "Perhaps they have a special tool for this? I can think of several pole arms that might serve to reach the lever."
