Dave, Fist of Odin
I start tapping - gently - on the walls with my mace. For two reasons - one, to search for any secret doors or panels, and two, to give the thinkers in the party some time to do that thing.
I do that for about 15 minutes. Then I spend 10 more minutes getting angry. I mean, filled with rage, and not like the badger. I know how angry that badger is. I mean AN GRY. I'm so far past the anger of the badger, that if the badger's anger was a line, it would look like a dot to me.
After that - well, I have some ideas for after that. But there's 25 minutes of light and shit first, if anyone has something else to do.
