Ch. 1 Back to Grimmauled's Place

Two figures entered the deserted house. They were wearing simple black robes and skull masks. They had been searching the area on the orders of their master. They found nothing and have gone to report to their master. They came into the front room of the muggle house. They still weren't sure why their master would want a muggle house. Wouldn't the Muggles come back? It wasn't one of the two men who spoke first.

"What news?" A cold voice said.

"All clear My Lord" The first man said.

"Good. Soon we shall make our presence known. The Ministry of Magic has been able to hush it all up until now. That will all change soon enough" A cloak figure came into light. The men obviously didn't think there was anything unusual about this.

"My Lord what is going to happen when the Muggle family come back" The second man, who was taller than the other, asked.

"They won't be coming back" The clock figure said confidently. The men looked at one another not daring to ask how their master was so confident that the Muggles wouldn't come back.

"What about the Aurors?" The first man asked. He hoped he wouldn't angry his master. It was clear to see this man had medium length blond, which was almost silver, hair.

"We shall kill any Aurors we come across. Are the others ready for the attack?" The cloak man had finally taken off his hood. The site it revealed would give anyone nightmares. His servants obviously were use to this site.

"Don't we need more followers?" The blond haired wizard asked.

"Yes but not now. When the time comes, I shall have plenty of followers at my disposal. All we need now is my pawn at the Ministry to follow through." The mask less wizard coldly with complete disregard for innocent life. There was a sudden appearance of a large serpent.

"What's that my Lord?" The second, taller, man asked.

"Her name is Nagini. I found her outside the village." The wizard said. The serpent rose up to be stroked by her new master. The other two men looked at the great serpent apprehensively.

"You may go now" He hissed to the man. The men immediately turned heal and ran. They were gone before the cruel wizard started speaking again.

"Very soon, Nagini." The man told to his pet. No one would have been able to know what he said to the snake. All they would have heard, if the gotten the chance, was hissing. The hissing would probably be the passerby's last thing they ever heard.


The summer sun shined down on the dark haired boy. He was medium height, and was very thin. At the moment he was sitting on a park bench look deep in thought. His gray eyes looked out a small family passing by. He wondered if they were really as happy as they seemed to be. Sirius Black; Boy wizard, Hogwarts student, and Marauder, certain wasn't.

"Excuse me" A man said politely. Sirius was started. He had never been addressed thus by a muggle, a non-magically person. He's parents have always forbidden him to talk to the Muggles here.

"Yes Sir" He said trying not to sound too started. The man looked deeply curious as to why a nearly 14 year old boy would be just simply sitting on a park bench all alone.

"My wife and I noticed you've been at the park for a little while, is anything wrong, can we do anything for you?" The man asked. Can you change who my family is, Sirius thought.

"No sir. Just enjoying the park" Sirius said. Sirius got up off the bench and walked down the street. He went in the middle of number 11 and 13 of his street. He walked up the same steps he walked up all his nearly 14 years.

"Finally, Mom and Dad were wondering you were out. You weren't in the Muggle Park were you" His brother Regulus asked with disproval.

"Clearly they weren't too concerned" Sirius said sarcastically ignoring his comment on the Muggle Park. Going to the park was the only thing that brought him any joy in the summer.

"Can you not do that" Regulus asked obviously annoyed.

"Oh you mean sarcasm" Sirius replied.

"You're impossible" Regulus said rolling his eyes. It was a common phrase in their house to use when describing Sirius. Not that Sirius cared that much.

"And your ugly" Sirius retorted. Sirius walked up the stairs and went into the bathroom. He took off his clothes and got into the shower. He was thankful that his parents were gone out. He supposes there was a party at somebody's house. He took off his muggle clothes and got into the bath. He tried to keep his mind from going anywhere near the danger zone. That was hard because it seemed like no matter what he did dangerous thoughts came in anyways. His thoughts went to the unanswered letters of his three best friends. He felt guilty for not responding to them but at the moment he didn't feel like he deserved to be associated with them, The Marauders. He didn't feel very like a Marauder at the moment.


Sirius got up the next morning not really expecting anything out of the ordinary to happen. He had gone to bed early but still managed to stay up all night anyways. Thankfully their family house elf, Kreacher didn't come in to walk him anymore. Sirius was considering writing a letter back to his friends.

"Morning" Sirius said as he went into the dining room. He was still very tired. He didn't really care if he's family responded but he thought it was polite to do it anyways.

"Morning" His family called. Sirius took a seat next to Regulus. He and Regulus haven't exactly spoken since he had gotten back from his Aunt Bellatrix. Not that Sirius had attempted to start a conversation. The moment he got back he shut himself up in his room. It had been such a horrible three weeks.

"We got your booklist the other day" His mother told him. Sirius nodded in understanding. He was excited to go back to school but he wasn't interested in conversation at the moment.

"We are getting your books and school supplies on Monday. It looks like you can use new school robes as well. I signed your Hogsmead form as well. Try not to lose it" Walburga Black told him.

"Yes mother" Sirius said not really paying attention. There was silence for a moment. His parents weren't big talkers.

"We are going out today. Your father was invited to a lunch by the Minister of Magic. Regulus is going by Narcissa's today for a visit. So you'll have the house to yourself today" She said rather coolly

"Fantastic" Sirius said taking a bit of eggs. It was what he needed right now, to be alone. Sirius knew his parents were still disappointed with him for making Gryffindor. It was the highest shame to them that he dared be in any house other than Slytherin. It was what led his parents to send him to his cousin to straighten him out. His brother Regulus on the other hand was the perfect son. Not wanting to be in his family's presence for any longer he went up to his room. Sirius closed his eyes and took feel asleep.

Two hours later he was woken up by a sound downstairs. It wasn't a loud bang more like a swish. Sirius knew what it was, the fireplace. He went downstairs to see who flooed in. There was no one there. Maybe I imagined it, thought Sirius. He walked up the stairs to his rooms. He closed the door behind him, fully intending on going back to sleep.

"Hey Sirius!" A polite voice said. Sirius jumped and turned around quickly, his heart pounding in his chest. The person whose voice it came from was shocking. Remus Lupin was his bedroom, sitting at his desk.


Next Chapter: Sirius tries to keep his uninvited visitor a secret from his parents. A conversation nearly leads to a revelation. Sirius finds out that he might not be the only one who is keeping a secret.
