(Since Eikka did all the detecting of magic, I dumped the stuff in her inventory, save for the alchemist's fire and lantern, since Snerp explicitly took those. I don't have anyone as having actually taken the cloak and orb, though you talked about it).
Roberts does a thorough job of hammering in the pitons into either side where the portcullis is set. It doesn't look like it'll be coming down any time soon.
As Eikka steps into the chamber, the chanting stops. It had been filling your ears for such a long time that the silence is temporarily disconcerting. The silence is so complete, it's as if something is holding its breath, waiting for the next steps.
The water is 2 feet deep. The ledges and central dais are 5 feet high (3 feet higher than the water's surface), and the chamber's ceiling is 16 feet high (11 feet above the dais and ledges). The chains dangling from the ceiling are 8 feet long; Half embedded in the east wall is a wooden wheel. The hole in the west wall leads to a naturally formed alcove. Half-submerged in the water is a pile of refuse that fills it.
