Sora did try to focus on the fight at the fort, but his attention was quickly diverted away from that. Finally, he felt like something was wrong. This was more than just feeling tiredness or being out of practice. It felt like all his energy was slowly draining out of him, like his Keyblade was extremely difficult to even hold. He stood slowly, feeling dizzy. "Umm..."

He started to walk back in the direction they'd come in, barely even acknowledging Xion now. "I feel funny..."

And then all of a sudden, the Keyblade vanished from his hand, and he collapsed onto the dirt, unconscious.

[Sora will be out of it until they at least get back to the SOL, and most likely longer. Up to you how much further you want to go!]
