Percy awoke the day after the 7 returned to camp. He was in his cabin, naturally, and has just had the craziest dream.
Now that he thought about it, he realized he had that dream before, about a year ago. He remembered it now, not very clearly, but he new it had done something to him. His skin buzzed with energy, and he felt like he could take Atlas' place holding the sky for at least a full hour. In short, he was pumped. He didn't know how, or why, but he did. Then he remembered.
'Temporary God' Gaea had said. So Percy was a God now? Good, he could totally get into this. He imagined a place - his mom's apartment - and he was immediately there. He was ecstatic, he could do anything he wanted. He flashed back to his Cabin and thought for bit.
Gaea had made him the new God of Time. He decided to give it a quick test; he looked at his fountain in the corner, which was always spurting water. He thought about the air around him thickening to no movement, to people outside standing stock still. Not even slowing down, the water stopped in midair. Percy stood and approached it. He ran his fingers through it and it flowed just like real water, if real water only moved when he touched it. It didn't even continue it's fall when he touched it, it simply moved out of the way. Percy resumed time, and the water splashed into the basin.
Unsure of what to do with his new abilities, he turned back to the rest of the room to change clothes. But in his excitement for his newfound powers, he failed to remember Annabeth had spent the night in his cabin. He approached her quietly, as not to wake her, for he had just gotten an idea.
