After stepping through the door, Sora didn't immediately find himself in another room. There was a few seconds where he felt like he wasn't really anywhere, or in some in between place, before he staggered out into...

Some kind of gym?

He blinked his eyes a few times, trying to dispel the dizziness. Sora had traveled by unorthodox means before, so he wasn't as thrown off as he could have been. Besides, the institute had decided to warp them around before, so this wasn't exactly new.

"So this is the third floor?" Somehow he'd been expecting something more... intense. Not an empty gym. But Landel probably didn't want them to arrive anywhere close to his actual location, so it kind of made sense.

He glanced back at the pad that they'd stepped off of, which glowed with a purple light. "So we have to find more of those, I guess." But for now, there were some doors they could go through, and that was really the only path available to them. Seemed pretty straight-forward.

The door led out to another balcony, like the one on the second floor, where they could see down into the Sun Room below. There was a sheet of glass, however, that meant though they could see down, nobody could see up. ... Too bad for Landel that hadn't been enough to keep this floor a secret.

From here, however, there were a lot of potential places to go. "Normally I'd suggest starting at the end, but I guess it doesn't make much of a difference in this case," he said with a frown. They couldn't methodically check through every room in a linear fashion like that when there was no predicting where any of the pads they found might take them.
