Here we go, I finally got my act together! Enjoy!
When Harry met Rosie
Rosie looked around and wished she hadn't. All of her possessions were little piles of dust on the floor and the remaining things were crumbling as she looked at them. She was afraid to look at herself, just in case, but she reasoned that she had seen herself before. .
She looked down. She was glowing faintly. 'Ah. So it wasn't my imagination then', she thought. She noticed a tattoo on her arm; a skull with a snake coming from its mouth. She didn't know what it meant now, but she would when he came. . .
Harry hurriedly got dressed and left his room, not forgetting his invisibility cloak and the Marauders Map. He crept silently down the hallway and kept going until he reached the courtyard, where he sat down and reached in his robes to find the map. 'I solemnly swear I am up to no good' he whispered to it. The map never ceased to amaze Harry as its secrets revealed themselves to him. He suddenly wondered why he had brought it; the girl wasn't in Hogwarts so the map would not be able to reveal her location to him! He swore and kicked the step. 'Mischief NOT managed' he said angrily to the map and went back to kicking the step. Suddenly the map started to twitch within his grip, he hastily dropped it as it grew to twice, then three times its original size to reveal something he would never have imagined possible. The Marauders map had just shown Harry everything, everywhere in the world. And then, there it was: her name; Rosie Hoffmann. The map showed her to be somewhere in 'Bury St. Edmunds', though where that was Harry had no idea. He decided to talk to Sirius about it and sent Hedwig right away.
Dear Harry,
I wrote as soon as I could, I'm sorry you had to wait for so long. About your dream – do not go looking for this girl- DO NOT! I mean it Harry, if you do-who knows what will happen. If it IS Voldemort, then he is luring you-you can't let him do this. Whatever you do-STAY AT HOGWARTS. IT'S NOT SAFE ANYMORE.
As for your other question, yes I am safe and well. I still cannot tell you where I am but don't worry about me. Try not to send too many letters as there are dangerous people here and Hedwig may get noticed.
I hope you are well and please don't do anything stupid.
Sirius
Harry re-folded the letter and put it with the others. 'I'm sorry Sirius' he whispered to himself 'I have to go'.
Once again, he stepped out into the courtyard, this time carrying his broom with the Marauders Map strapped firmly to its handle along with the few belongings he would need. He had told Ron and Hermione that he was going to find someone. He didn't tell them the whole truth though; the fact that he had no idea whatsoever where to start looking or that he was going into the muggle world again. Harry left silently. Not a soul knew where he was.
