Kismet, naturally, begins to climb up the vertical passage, being cautious about the wooden rungs, as they clearly feel weakened with dampness and perhaps rot. He grips and steps upon the corners of the rungs, warning the others as he goes, though of course they begin to sense this as well.
Yet the rungs hold as Kismet climbs through the twisting chimney, until above, some twenty feet or so above him, he can see something that looks like a rattan-work covering. There is a dim light showing through the rattan branches. He cannot hear any sound or sense any movement. After some natural whispering with his friends, he will eventually move up until he can see that it is nothing more than a covering over the chimney, not hooked by hinges in anyway. The light seems to correspond to daylight.
All continues to be quiet. What do you do?
