Percy didn't have any memory of leaving the temple. He simply opened the path out for the others then disconnected himself from the generator circle.
The moment his hands left the Spellcore connected to the center of the circle his vision went black.
He woke up a short time after. His body was on top of something that kept shaking and his eyes felt too heavy to even move. So he went back to sleep.
The next time he woke up, the world was stable and there was something hot beside him. But this time his limbs felt wooden and painful to move so he went back to sleep.
He went through the cycle a couple of times before his body finally felt like his again. When he woke up this time, his body hurt but it wasn't impossible to move. He opened his eyes slowly.
It was night.
