Disclaimer: I don't own any concerning the Percy Jackson world. And just like my story, The End, I uploaded but deleted this because I hadn't finished it. It's up again because I was bored and read through my old stories.

Zack grinned to his two best friends, Alex and Marcy.

It was the last day of school as eighth-graders at Youth Grades High, and they were planning a little prank on the rest of the school.

"This is going to rock," Alex said. She clicked her fingers and watched as a tiny flame appeared on her hand and danced across her palm.

"I think that we can all agree that this school deserves this?" Marcy asked. Then he, too, clicked his fingers, and a small fire-ball appeared over his hand, and stayed stationed there. He attempted to move the fireball, like Alex's flame, which was still dancing merrily across her hand. He then groaned angrily and clicked his fingers again, so that the fire disappeared.

"You just need practice," Zack said. "Alex, you weren't always able to make the flames so graceful, right?"

"Yeah," she said. "But mine never just floated above my hand. It used to fall onto the ground and cause forest fires." She laughed cruelly.

"It was quite difficult to extinguish," Zack added, smiling to himself. He then shot a jet of water into the air and the trio of friends laughed as it rained down on them.

They stopped what they were doing abruptly and, for the thousandth time, wondered why they were able to influence water and fire respectively.

"It's just magic, isn't it?" Marcy asked. "Maybe we're magicians."

Zack snorted, "My Mom is an accountant. I don't think there was any magic in her blood."

"What about our dads?" Alex asked. "We all never knew them. They might've been wizards or something."

Suddenly, from inside the school Assembly Hall, the kids started clapping drearily- something that signalled that the Headmaster had now gone on stage.

"Now's our chance," Marcy said. "Let's get 'em!"

As one, he and Alex clapped their hands once.

All the doors and windows to the Hall burst open, and suddenly, in less than two seconds, the entire Hall was in flames.

The trio laughed evilly as hundreds of screams erupted. Fire was blocking all the exits, and chaos had broken out.

Zack walked closer to the nearest exit and examined how it looked inside.

Just above the stage, a fireball (summoned by Marcy) was hovering twenty metres above the ground. It was just for show, because Marcy did not know how to make his fire move, but the effect was great.

Alex had created hundreds of flames that danced around the hall, giving the illusion that the Hall was on fire. In those numbers, the flames no longer looked pretty.

Zack suddenly felt a spasm of fear for those inside.

"What if they get burnt?" he asked Alex and Marcy, but they just laughed.

"My fireball could kill them on contact, or make them die of a heat-stroke, but no one in there is twenty metres tall," Marcy pointed out.

"My flames don't burn, unless I will them too," Alex said. "As much as I hate this entire school, I don't want to kill them. Just scar them for life."

It was suddenly Zack's turn in the prank. Out of nowhere, he summoned hundreds of litres of water to appear above the Hall. The water dropped at once, and found its way into the Hall, distinguishing all Alex's flames and even killing Marcy's little Sun.

As water rushed down to pulverize the three friends, Zack summoned a large bubble which protected them all. The water looked quite feeble once they were safe inside the bubble.

The same could not be said for the students and teachers of Youth Grades High. The water had washed them all to the ground, and they all looked completely disorientated. With a pang, Zack noticed that the Headmaster seemed to be unconscious.

This was no longer a small prank. They were in serious trouble.

"Hey!" a voice yelled.

The trio spun around, but instead of seeing policeman coming to arrest them, they saw Grover Underwood, an eleventh grader of Youth Grades High.

Grover was completely drenched, but how he managed to get out of the Hall unscathed and so quickly, neither Zack, Alex nor Marcy knew.

"Oh, gods," Grover muttered. "Why do I always get the most powerful ones? First Percy, then Thalia, then Nico and Bianca, and now these three."

"What the hell are you talking about, dude?" Marcy asked.

Grover looked at them seriously for a while, and then he took a deep breath and said, "We need to get you to camp. Chiron needs to see you."
