Percy wandered aimlessly through the woods behind his house. Hecate had given him the day off. Something about doing work constantly not being good for you.

He pulled Riptide out of his pocket and inspected it for what seemed like the millionth time. Something about seeing it in a wand form felt... weird.

Riptide had always remained constant ever since he had received it from Chiron all those years ago. It stayed the same 3-foot long nigh-indestructible leaf-shaped Xiphos that it had always been. Even as people around him died, monsters were slain, and even the gods had their share of changes, it had always remained the same.

Now it wasn't.

Instead, it was a stick. Granted, it was a magic stick, and magic is cool as hell, but it was different, and he wasn't sure how he felt about that.

It seemed sort of like a metaphor for how his life had been going. On one of his first encounters with the Greek world, he had received Riptide. It had remained his companion for all those years. Now, as he left the Greco-Roman world, it changed alongside him.

Now he was in a different dimension, learning magic, so he can help some guy defeat an evil wizard.

Funny how life changes on you like that.

"Uh, hello?" a voice said from in front of him.

Percy slipped Riptide into his pocket, silently chastising himself for ignoring his surroundings.

"Hello there," he says, looking up towards the figure.

He had black hair and bright green eyes, much like his own. However, that is where the similarities stopped. This person had a thin face and wore a pair of round glasses.

"General Kenobi," the person said.

Percy had a confused look on his face, and so did the other person.

"My name is Percy," Percy said, sticking out his hand, "Percy Jackson,"

The person shook it hesitantly, "My name is Harry Potter,"

They stood in silence for a moment.

"So uh, are you going to stop shaking," Percy asked.

Harry immediately pulled his hand back, "Sorry..."

Percy laughed, "No, it's fine,"

"So, what are you doing here?" Harry asked.

"I'm on a walk. What are you doing here?" Percy retorted.

"I'm doing my best to postpone going home because my family is evil," Harry said.

Percy blinked.

"What?" he said. That was not what he had expected.

"I'm doing my best to postpone going home because my family is evil," Harry repeated deadpan.

"That is... not what I was expecting," Percy said.

Percy frowned, "Are they the actually evil kind of people, or just really negligent,"

"They make me live in the cupboard under the stairs,"

They sat in silence for a moment while Percy thought.

Percy grinned, "I have an idea. Why don't I go get a couple of things, and I will meet you back here in a few minutes,"

"What?" Harry asked, but Percy was already running.

Percy handed Harry a small bottle.

"What is this?" he asked.

"Basically, laxatives 2.0," Percy said with a mischievous twinkle in his eye, "One could almost say it's like magic,"

Harry looked at the label on the bottle.

"Zonko's Perfect Poopers?" Harry read aloud, "What kind of name is that?"

"The names might not be the best, but they make the best pranking supplies," Percy said, shrugging.

"Hold up, pranking supplies?" Harry stopped, "You want to prank my family,"

"Yeah, I'm not one of the Stolls, but I learned that a good prank or two can go a long way," Percy said, smiling wistfully.

Harry gave Percy a weird look but agreed.

Percy smiled and did that supervillain thing where he tapped his fingertips together, "Eeeexcellent,"

"So here's what we're going to do,"

"Bwahahaha, did you see the look on their faces," Percy said as he and Harry stood outside Harry's house.

"OK, I'll admit, that was pretty funny," Harry said with a massive grin on his face.

"Perseus Jackson," a deathly calm voice said from behind them.

Percy froze and then slowly turned around.

"Uh, hey Hecate," he said, "I was just heading home..."

"What exactly have you been doing for the last hour?"

"Um, excuse me, who is this?" Harry asked.

"Oh uh, Harry, this is my... cousin Hecate," (Godly family trees are confusing AF, I'm pretty sure she's his cousin or niece depending on the particular myth)

"Hello, Harry," Hecate stuck her hand out, "Nice to meet you,"

"Hello, Hecate, I'm Harry, but you already knew that," Harry said, shaking her hand.

"What have you been doing?" she asked, "You were supposed to be home much sooner than this,"

She gestured towards the now setting sun, "It's been over an hour, I thought you managed to..." she glanced towards Harry, "get kidnapped or something!"

"Sorry, mom," Percy sassed, "we got sidetracked pulling off a revenge prank on Harry's step-parents,"

"Don't you be talking back to your mother like that!"

Harry shifted awkwardly, "I should probably get going. It is getting kind of late,"

"Oh right," Percy said.

They stood in silence for a moment before Harry started slowly backing away towards his house.

"Bye,"

"Bye, see you soon!"

As soon as Harry left, Hecate started laughing.

"What's so funny?" Percy asked, "And don't you dare say my face,"

"That-haha-is the person you're supposed to help-hahaha," Hecate replied, laughing.

Percy blinked, "Out of everyone in England, I manage to run into the one person who I need to help,"

Hecate's laugher started trailing off, "Well, not exactly. I knew Harry lived nearby. That's why I chose that spot to put the access portal,"

"Oh," Percy said, "So should we be getting back now?"

"Yeah, probably, don't want to run into any werewolves," Hecate replied as she started walking away.

"Wait, What!"

The camera starts zooming out. And that was how the rest of Percy's summer went, learning magic, playing pranks, and having it pretty good. The end.

What? You wanted to actually read the rest of the story? Ugh, fine.

September 1st, 1991,

Percy tossed all of his clothes in the suitcase. He ran out to the table in the kitchen before grabbing a couple of textbooks and tossing them roughly into his suitcase.

He still didn't understand why he couldn't use a backpack or something, but when in Rome, do as the Romans do...

Oh, the books weren't damaged by the way, and the suitcase wasn't even close to being full. Dimensional magic was awesome like that.

Percy carefully placed the magical glasses he had been using back in the case, and then lightly placed them into the suitcase. It worked well for non-magical substances but got more unstable the more magic you packed into it.

Hecate said it would be fine for the glasses and a couple of other things, but he shouldn't try to stick his wand in it or something...

An hour later, he was standing at the door, holding his suitcase ready to go.

"Hey! Hecate, I'm ready to leave!" he shouted, "Where are you!"

A couple of moments later, Hecate ran down the stairs.

"I'm coming, I'm coming," she said, "Jease, kids these days have no patience,"

Percy rolled his eyes, "Come on old-timer, I don't want to miss the train,"

"Right," Hecate said, producing her wand from her sleeve, "I shall now apparate us to King Cross Station!"

Percy touched Hecate's other arm, "When can I learn how to teleport?"

"First, it's apparating, not teleporting. Second, it's illegal for you to apparate until you turn 17," Hecate replied.

She flicked her wrist, and they were off.

Apparation is a rather difficult manner of transportation to master, and few bother to even try. Many a wizard have ended up in a... less than an ideal condition due to a botched apparation, which does not help the appeal. Most of the risks, of course, don't apply when you are traveling with the Goddess of Magic herself.

Instead, Percy had to contend that he felt like his stomach felt like it was now inching its way up his esophagus.

Percy straightened slowly, "Woo, that was much worse than shadow travel,"

Hecate patted Percy on the back, "Yeah, apparation isn't the most stable method of teleportation,"

"I'll say," Percy muttered, then he looked around for a moment, "Where are we?"

"We are currently in the alleyway next to Kind Cross Station," Hecate replied, "This is where most wizards apparate to before they head in,"

"Right," Percy said, "So we just walk in?"

"Yup," Hecate said, shrugging.

And they kept walking until they reached the column in between platforms 9 and 10.

Percy looked up and down the column, "So you want me to run headfirst into this very solid looking pillar,"

"I wouldn't have put it exactly like that but... yes," Hecate said.

"Hell no,"

"Come on, I'm not tricking you this time,"

"This time?"

As they stood there arguing, someone else had been coming up behind them.

"Uh, Percy?" Harry asked, "What are you doing here?"

Percy and Hecate immediately stopped arguing.

"Yeah, um- I'm also a wizard, surprise," Percy said throwing out his hands, "I was sort of in charge of making sure you don't die over the summer,"

Percy shrugged, "Luckily, I was not required,"

Harry stood there flabbergasted, "So what, was my friendship with you just a lie?"

Percy immediately had a flashback to when he found out Grover was a satyr. Come to think of it, they didn't really talk much after the whole Polyphemus incident. Makes you wonder if this is really the best way to keep track of important kids...

"Percy!" Harry hissed, "Are you ignoring me!"

Percy snapped back to reality, "No, no, I definitely wasn't,"

"He totally was," Hecate said.

"Shut up," Percy whispered, elbowing Hecate in the ribs.

Harry looked at Hecate, "Were you in on this too?"

"Well yeah," she said shrugging, "I live with him, how is he supposed to keep it a secret,"

"Very, very, carefully," Percy muttered, "Look, Harry, can we talk on the train? I really don't want to have to explain why I was late on the first day of school,"

Harry groaned, "Fine. But I want answers,"

"Of course," Percy said.

And that's a wrap.

So, hi, it's been a couple of weeks, and I am back but I'm probably going to starts updating slower than before. I will do my best to update at least every other week, but please don't expect too much.

Review and stuff please.

P.S. In case you were wondering, the names in chapter 2 were referencing DelayedInspiration's stories Xenomorphic, Backup Plan, and Leviathan. If you're ok with more... adult themes, they're awesome, go read them (He's got a bad habit of turning all of his characters into morally ambiguous mass murderers with way more power than they should have, but the dude is a writing genius)
