Privet Drive, Little Whinging, Surrey

11:59 pm

It was eerily quiet in Privet Drive; no-one was awake, and the night-time creatures seemed to be avoiding the area.

The sole exception was a cat, a cat that was sitting on the stone wall that divided number 4's front yard from the sidewalk, staring intently at the end of the street.

The church clock in the distance started toning.

Precisely at the stroke of midnight, two things happened at once; Albus Percival Wulfric Brian Dumbledore appeared at the corner with Wisteria Walk.

And a young man wearing blue and black clothes stepped out of the shadows in front of number 5.

Albus pulled out a silver lighter, and clicked it. The magical device sucked the light from each lamppost one at a time. Soon the only sources of light were the eyes of the cat, two pinpricks of light that were soon joined by a glowing stick.

"Minerva," Albus greeted, nodding to the cat, who was replaced instantly by a slightly older woman wearing a cloak and robes. He then turned to the one clad in blue. "Riley."

"Albus," she acknowledged, "How did you know it was me?"

"My dear, I've never seen a cat sit so stiffly."

Minerva sighed.

"You would be, too, if you'd been sitting on a stone wall all day," she said irritably, "I've been watching the Dursleys carefully; we can't leave him here. Petunia Dursley absolutely hates her sister and anything to do with magic. Her husband is exactly the same, and their son is a spoilt little brat and a bully. He kicked his mother all the way down the street, screaming for sweets."

Albus winced.

"We don't have many options," he explained, "Lily sacrificed herself for Harry… and besides that, I doubt she would want her son to grow up spoilt… but given what you've just told me…"

"He won't be treated well here," Riley said, frowning, "But what about the Longbottoms? And why not Sirius? I managed to head him off and we sent Aurors after Pettigrew."

"Sirius has to go into hiding; that's not the sort of environment suitable for a child," Albus explained, "The Longbottoms… were attacked early this evening. I'm afraid they're in no condition to be looking after a child."

"You don't mean…" Riley asked, his heart in his throat.

"They're alive, but… comatose," Albus said heavily, "And the Healers doubt they'll be in any condition to look after a child after they wake up."

"What about Ted and Andromeda? They adore Harry," Minerva questioned.

"Not a good idea, unfortunately," Albus grumbled, "I wish it was, but Ted is a news anchorman…"

"I'll take him, then," Riley said, holding up a hand to forestall argument, "Harry's a complete unknown in my world, and I know a couple who would love to adopt him. Plus, if his Aura develops the way I think it will, he can be my apprentice. I can take Sirius along, as well. Remus, too, if he's willing."

Albus perked up.

"Excellent idea," he said, clapping Riley on the shoulder, "Minerva, if you would…"

"Certainly," Minerva said, happy to comply; she vanished half a second later with a barely audible pop.

"Where is Harry, anyway?" Riley asked.

"Hagrid is bringing him. He borrowed Sirius' bike…"

Minerva chose that moment to reappear, along with two more men, both wearing robes. One had neat, sandy-coloured hair, while the other had slightly longer black hair.

"Riley!" Sirius Black, the dark-haired man, greeted, shaking Riley's hand warmly.

"Sirius, good to see you," Riley said, smiling, "You too, Remus. How'd you find them so fast, Professor?"

"Time turner," Minerva said, smiling sheepishly, "Now, where's Hagrid?"

"He's a tiny bit late," Albus said, checking his watch; the moving planets and multiple stationary arms made no sense to Riley at all.

Seconds later, the growling of an engine reached their ears.

"That'll be him," Sirius said, looking up. Everyone else looked around for a headlight, then followed his lead looking up.

A motorbike fell out of the sky and landed with a squeak of protesting suspension.

With a chuckle and a shaken head, everyone went over to the bike, and its huge rider.

"Professor Dumbledore, sir," Hagrid greeted, "Sirius, Remus… Riley!"

He grabbed the young man and pulled him into a tight, if one-armed hug; his other arm cradled a bundle of blankets.

"Good to see you too, Hagrid," Riley laughed, freeing himself.

"There's been a change of plans, Hagrid," Albus said, "The Dursleys aren't suitable, so Harry will be going with Riley."

"Sirius and Remus are along for the ride," Riley explained, "I know a couple in my world who would absolutely love to adopt Harry. Plus Lani would absolutely love you two pranksters," he chuckled.

Hagrid handed Harry to Riley, and the young Aura Guardian brushed the blankets aside, noting the cut on the baby's forehead.

"A curse scar," he noted, frowning. He then closed his eyes, and concentrated. A faint blue corona formed around him and Harry. The baby slept on, oblivious, as a black substance bubbled out of the cut, getting startled and disgusted looks from the others.

"A horcrux?" Albus asked, knowing Aura channelling was the only way of destroying a horcrux without destroying the host object, "Inside Harry?"

"Isn't it hurting Harry?" Remus asked, worried.

"It hasn't had time to anchor yet," Albus explained, "It takes several days to anchor properly to another living thing. What worries me is that he was making one."

"It's gone," Riley said, as the black tar-like substance started evaporating into thin air, "And now I think it's time to go."

A slowly rotating blue vortex formed on the Dursleys' driveway, and Albus leaned in closer, fascinated to see the power he'd heard that Giratina had.

"If you need us, we'll be at Draconia Sanctuary in Alto Mare," Riley said, bowing slightly. "Un-."

"Mew!"

Everyone turned to look; a vaguely cat-like creature had come out of the portal and was hovering in mid-air.

"Myuuuu!" it giggled, circling each of them, before settling in front of Harry, who had woken up and was gurgling baby speech at the legendary Pokémon.

"Dear Arceus!" Riley whispered, shocked, "I know Giratina brought me here, but I never saw it… This is Mew, a Legendary Pokémon. Only a very select few have ever seen it."

Mew rested a hand on Harry's curse-scar, and glowed pink; everyone watched, wide-eyed as a faint gold line appeared on each side of Harry's neck, and his shock of black hair just barely started for form four spikes.

"Rayquaza's blessing?" Riley breathed, "Mew, did Rayquaza send you?"

"Myyyuuuu!" the little pink cat creature giggled, doing a somersault. Then it dove back into the portal, disappearing instantly.

Riley sighed; "Well, I guess that's probably par for the course with Mew… Sirius, Remus?"

"See you next time, Professor," Sirius grinned, before jumping into the portal.

Remus shook his head, before giving Albus and Minerva a handshake, and Hagrid a quick hug around the stomach (the highest he could reach), and jumping in himself.

Riley bowed slightly to each of those present.

"Until next time," he intoned, before jumping into the portal. Seconds later, the portal was gone without a trace.

"I think it would be best if we left as well," Minerva said, "Hagrid, could you take that bike to Sirius' house, then catch the Knight Bus back to Hogwarts?"

"Um… sure thing, Professor," Hagrid said, looking a little queasy at the thought of the bus.

"Very well then, I'll see you when you get home, Hagrid," Albus said, before he and Minerva vanished with quiet pops. Hagrid restarted the bike, and shot up into the air.

A few seconds later, a single owl dropped its letter neatly into the Dursleys' letterbox.

No-one would ever know of the strange and mysterious things that had occurred on their very doorstep.

Perhaps it was better that way.
