TAKSHAKA
[The room you step into looks like it could be a miniature ballroom, complete with stained glass windows and vast, ornate mirrors.
Your team's column is set into one wall, easily accessible but as impregnable as ever. One of the mirrors may prove almost as interesting, if you can tear your eyes away from your trapped teammate. Through it, you are somehow able to see every other team's column and what is inside, though nothing beyond that.
The floor beneath your feet polished, patterned wood, inlaid with the pattern of a grand sundial in your team's colors. In the center of the pattern stands a pedestal, upon which sits a collection of colorful glass ornaments. It looks like there's room for other items, but there's nothing else to be found just yet . . . ]

AND THEN
. . . eventually, when your hostage is well and truly drowned, the glass begins to crack. You'll be able to retrieve the body if you give it a good kick.
You may proceed to endgame and/or revivals]
