[ Istredd follows him and steps forward to put his hand on the wall. Now it is much clearer, although he still can't see what Claude does. He moves his hand over to where Claude is suggesting and only then does he feel it, clear as day. His eyes widen and he runs his hand along it. ]

I feel it. I still can't see it, but you're right, it's here.

[ If Claude was still doubting his sanity, this confirmation hopefully helps. Istredd can tell it's not big enough to go through now, but with help. Hm. He pulls away and considers. ]

The problem is that we're going to draw attention if we try to jar it open. I'm not sure if we need to smash down more to get through, or if there's a secret to it, but ... the acolytes might come down on us fast.

[ Istredd can't think of how they could make this subtle. It may be that they can only attack this point when everyone has the freedom to potentially deal with a push back from their captors. ]
