AN: This takes place in the seventh year at Hogwarts. The war isn't going to happen in this story, everything is normal.

Nico was silently crossing the dark streets of London, wearing an oversized black coat to keep him warm. It was harshly cold, even though it was just the last week of August. Britain had the strangest type of weather.

He was not afraid of being hurt or attacked, he was of course a trained demigod. Though Nico was wary that something was following him, something...not really human. Nico would often turn his head to see behind him, nothing in site, but it raised his defenses even more. Nico often tried to relax and just calm down, he would be fine.

As the streets became more abandoned, the more likely people like drug dealers, or murderers would be out prowling in search of a stupid enough person to be out here. Nico decided to find an open store, he could house there for a while, then shadow-travel back home.

He moved his feet quickly to a section of the town Nico has never seen before. Bewilderment flashed on the teen's face. What in Hades is this place?

As he continued down the sidewalk, he focused his attention to a street sign nearby. 'DIAGON ALLEY' it said. Diagon Alley? Nico thought. He never heard of that name before. Where was he?

He stared at each of the store names, each one more creepy than the last. Flourish and Blotts, The Leaky Cauldron, The Daily Prophet office, Gringotts Wizarding Bank, Quality Quidditch Supplies, Weasleys' Wizard Wheezes? The shops seemed so old. He peered into the Quality Quidditch Supplies store to be greeted with a bunch of brooms, all different colors and lengths. On the tags he saw that each were a different speed.

Nico was now really worried. Were these...flying broomsticks, like in those tales of crazy witches? He backed away slowly, his body shaking slightly. Nico pondered for a moment if he should go home, or explore more. The whole place seemed so tempting, like your favorite ice cream flavor. Nico knew he should continue on, maybe he could discover something amazing.

Trudging past the rows of stores, he curiously stopped at Weasleys' Wizard Wheezes. It seemed very much like a joke shop. Bringing his face closer to the glass, he inspected each of the products lined down. There was some candy laying there too, each having half of a color. What did those candies do? Were they regular candies, or some crazy magical candy that could make your head explode?

A small 'whoosh' popped by and Nico turned his head to see who it was. Nobody...again. Nico sighed. If this was some idiot's idea of a joke, it wasn't funny.

"Okay you, whoever you are. Stop stalking me, I know you're out there. This joke you're playing is getting stupid. Go and find someone else to bother." Nico scanned the empty street. "Never mind, but just leave me alone."

Nico felt something. Something weird, as if something was controlling his feet. Without thinking, his feet started running and lead him off to a even darker and more sketchy area. Good for Nico that he had great night vision. There was a rusty marker out there that said 'KNOCKTURN ALLEY.' Knockturn, that word just triggered something in Nico's brain.

Before he could decipher the word, something hard hit him in the back, paralyzing him for a second. He tried to move his body, but it was as stiff as a board. His lips couldn't move either.

"Look here, there is a little boy running down Knockturn Alley. Did you lose your mommy?" The person teased in an obnoxious baby voice. Nico was angry and frowning on the inside, he was sixteen! He didn't deserve to be treated like a kid. The guy also had a British accent, not that strange because Nico was in London, or he hoped he was.

"You must be some Muggle." The figure said in disgust, as if Muggle were some hideously gross disease. Nico had no idea what the guy was talking about. Unfortunately, the guy was partially right.

"Ha ha, you can't move!" This guy was seriously getting to Nico's nerves. If he could move a single muscle, he'd punch this guy straight up in the face.

"Na, na, n-" There was sudden quiet. Nico went wide eyed. What happened to Super Annoying Guy, otherwise known as SAG? Nico was forcing the cells in his brain to start moving, and fast before whatever made SAG disappear, or Nico imagined that happened, made Nico poof out of here too.

Out of nowhere, something hit Nico very hard in the back again, and as Nico fell to the ground, all he saw was something drag him away right before he passed out.
