A short story on what could have happened on the day when Harry got out at the wrong floo and hid in a cabinet.
Disclaimer: I own nothing. Harry Potter belongs to J.K. Rowling no matter how much I would like him to be mine.
The Mirror
A glass case nearby held a withered hand on a cushion, a bloodstained pack of cards, and a staring glass eye. Evil-looking masks stared down from the walls, an assortment of human bones lay upon the counter, and rusty, spiked instruments hung from the ceiling. Even worse, the dark, narrow street Harry could see through the dusty shop window was definitely not Diagon Alley. The sooner he got out of here, the better. Nose still stinging where it had hit the hearth, Harry made his way swiftly and silently toward the door, but before he'd got halfway toward it, two people appeared on the other side of the glass - and one of them was the very last person Harry wanted to meet when he was lost, covered in soot, and wearing broken glasses: Draco Malfoy. Harry looked quickly around and spotted a large black cabinet to his left; he shot inside it and pulled the doors closed, leaving a small crack to peer through. Seconds later, a bell clanged, and Malfoy stepped into the shop. – Harry Potter and the Chamber of Secrets
Harry hurried into the cabinet not wanting to be seen by the Malfoys. If they found him he knew it would not turn out well. While the cabinet was not very spacious, Harry was used to small spaces since he lived in the cupboard under the stairs for most of his life. As he entered he noticed a small hand mirror that shone in the dim lighting. Curious, he picked it up, wanting to examine it closely. At that moment he started to experience a strange feeling, almost as if something was tugging at his navel.
Harry could not figure out what was happening until the spinning finally stopped and he fell to the ground. When he looked up he realized he was not in the cabinet as the originally was.
'Where am I?' he wondered.
The first thing Harry noticed was the unbearable chill that was in the air and the sound of insane rants. He was in some sort of cell and it didn't look like he was alone either. In the corner of the cell was—a dog? Harry stared at the large black dog, still unsure what had just happened.
Suddenly the dog woke up and looked at Harry in the strangest manner.
'It almost looks as if it recognizes me, but that can't be possible. It's just a dog.'
The dog continued to stare at him for a minute until all of the sudden he turned into a human.
'He must be one of those things that Professor McGonagall is.' Harry thought, remembering his first Transfiguration lesson.
The dark haired man stood up.
"James?" he croaked, for he had not used his voice in many years.
"No, I'm Harry. Who-who are you?"
"Harry? Is that really you?" the dark man asked.
Harry nodded, still confused. 'Who was this man?'
Suddenly, the man walked up to him and embraced him.
"Oh Harry, it is you. I haven't seen you since you were a baby." the man sobbed.
"I don't mean to sound rude, but who are you?" Harry asked.
The man broke into a sad smile, the first in over ten years. "I am Sirius Black. I am your godfather."
AN: That's the first chapter. I am not sure if I should just leave it as it is or write a few more chapters.
