Well, since the water has a long way down to go after it passes everyone's doors, the hallways are going to be bubbling brooks all day while the storm is raging and clear but damp after it passes.

The Heart room and warp room are going to need some pumping, though, so that's very doable.

Going on a hunt down into the belly of the Temple for other places water may have settled will take a very long time and uncover nothing but questions, woe, and - oh hey what's this.

It's the workshop/storage room where Tiger's been keeping the components for the warp pads while she works on them. The room is badly organized, but it's full of the building blocks of Gem technology.
