Theo skips sleep pretty often, so when he does actually sleep he tends to sleep for a while. Kaede will probably wake up before he does.
Okay. He's gonna back away from the building, then, and keep note of where he started – is it obvious and noticeable or should he build something to mark it?
He is going to put a small red cube next to it anyway! Just so he knows that it's the right noticeable exit!
Then he'll continue onwards. Any people?
Any interesting buildings that look slightly less dream-like or whatever on close inspection? Or perhaps interesting buildings that do look dream-like but that might be interesting on the outside anyway?
Anything written?
Does the city spread outwards from the platform, or is it all conveniently on one side of the platform? Because he will go explore this way for a while and then he will go try back the opposite way if this side gets too weird.
It is very solid!
And there's a man standing there, now, with his arms folded and his back to Theo. He wasn't there a second ago, but he didn't really appear. It's more like he'd always been there, but Theo hadn't noticed. The man is shirtless and barefoot, and his stance fails to hide the armour covering his left arm.
The man turns around to face Theo, revealing a muscled chest tattooed with a symbol that looks exactly like one Theo's seen on Tidus' shorts.
"Who're you?" the man asks, looking confused.
He does not remark on Theo's nudity.
"Theo," he responds. "Who are you?"
He makes no comment on the other guy's (half-)nudity, either!
"Couldn't there just be nobody who is Sin?"
If he tries to turn a piece of the man's clothing blue, does anything happen? What about a piece of his skin, change the color briefly.
Nothing happens. Man's as magical as the rest of the place.
"Ain't that a thought. If you figure out a way to do it, be sure n' tell me. I had a friend once who... Nah."
