Brenar:
As Colm and Dann(?) get the shield ready, Brenar fishes his rope out of his bag, and slip one arm through the coil. I'm ready. Are you ready?" He asked before climbing on the shield.
Brenar is lifted into the air and keeps his balance on the shield, about 5m above him he can see a solid wooden trapdoor. He decides to risk trying to ascend the rest of the way....
He easily wedges himself in and is able to shuffle up the rest of the shaft with his back against one wall and his feet against the other. When he reaches the top he notes a recessed bolt is holding the trapdoor in place and attempts to slide it across with the point of his dagger.
He does so with exceptional ease, and fastens the rope around a support beam, letting it down to give his companions a way up.
Carefully pushing the trapdoor up slightly he wedges himself in securely and peers through.
The room above is dusty and unlit but some sunlight does penetrate the windows and gaps in the timbers...
