Who: That's for nobody to know and nobody to find out.
What: A bit of redecoration.
When: About now in GrownHP.
Why: Because things really needed to be spruced up a bit. And you put a rebel in charge and expected him to stay quiet? Seriously now.
Author Notes: I'll get around to that Order meeting, promise. Sirius just has some business to attend to first. Wouldn't do to have everyone attached to such a stunt, now would it?
It was a few days after the bubble attack on the Ministry and more important, the news he'd gotten from his godson about Hogwarts and the plan to close the school. They had never closed the school, not except for after the war, for repairs and to allow the students time with their families. Of course it wasn't public knowledge that it would be closing this term...yet.
He had no plans to spread the news, either. Not with such a stunt that could be tied to him, as vauge as the ties might be when he was finished.
Of course they had extra security at the Ministry, extra Aurors on duty, but unfortunately, as good as the Aurors were, there wasn't much you could do when you were dealing with the only man to escape Azkaban. Not to mention that he was dead. Ish.
That little detail did have advantages at times.
Like the middle of the night, as he made his way through the halls of the Ministry, backpack on his back, no wizarding cloak, just his trusty leather jacket. There was no reason to hide his face, because it wasn't like anyone could see it. Sure, they had security measures in place but when you were one of the best trained wizards in the world (by your own years of experience thank you) you knew how to avoid them. They wouldn't get him on video or photograph or seen by an auror and caught. That would just be foolish.
The first thing he did was make a stop near the office of one Matthias Heim, and slip through the door (handy thing, being dead) and drop his backpack on a chair. It only took a moment to shake himself into a more comfortable form of being, and then, he got to work.
The corner of Heim's desk would be marked by several moments worth of having a go at the fine wood with sharp canine teeth. Dirty pawprints were then tracked all over the floor, nails scratched up against the walls, and his leather chair would be covered in a fine layer of black fur when he returned. Left in the center of the desk was a yellow tennis ball, covered in drool. Sirius refrained from leaving another 'present' for Heim to find, perhaps in a corner of the closet. After all, there was always next time.
No papers were put out of place. The plants remained upright and hadn't been spilled. It seemed as if the beast could walk upon the air while roaming the office, not disturbing anything important, just the minor damage to the desk and the hair left on the chair. Deliberate. Calculated.
Not the work of a beast.
Sirius resumed his walk through the Ministry, using his unstickable-sticking charm to plaster stickers with the red logo of a Phoenix to mirrors, bricks, floos, and yes, even the fountain which had been bubbling over just a few days prior. This was nothing compared to the trouble Sirius Black could cause when given motive, but he didn't really want to cause trouble.
Merely send a message.
Perhaps it was the wrong message to send. Perhaps advertising that the Order of the Phoenix had risen again would do nothing but give them less openings into the world of the Ministry than he'd had before. But Sirius didn't care. Those who kept quiet were the ones who would end up frozen to the spot as Heim ripped apart the Ministry and tore through the ranks of his friends and companions.
Remus had been singled out. Now Heim was going after Death Eaters and those who had been loyal to the Dark Lord (or still were, for that matter). Who was to say that he wouldn't choose to go after another party next?
He had to be stopped.
This? Was merely a calling card. If Heim wanted a wake up call, well then, Sirius would be more than happy to give it to him. But for now, he'd wait.
Of course, Sirius had taken a cue from two very famous Weasley brothers, and the next morning, as most members began to file into the Ministry for work, a barrage of fireworks exploded into the sky, all brilliant colors of reds and oranges, yellows, and a hint of blue, taking the shape of a phoenix. Wings fully extended, moving towards the sun.
(You couldn't have expected him to keep away from the fireworks completely.)
