Remus didn't really have time to consider what might have just happened. He could only presume that he had accidentally touched a portkey, but the how hardly mattered much when one considered the scene that he was seeing in front of him. The world that had once been tranquil was thrown into turmoil in a confusing mess of dust, blood, flashes of curses, and shouts and screams and...
It was Hogwarts. At least, from most angles it seemed like it was Hogwarts, but something wasn't right about it - other than the apparently raging war. He knew that things were bad out there, he was no fool, but how had it escalated to this so suddenly?
Questions later. For now, Remus was proving the sorting hat right by taking out his wand and running towards the battle and not in the opposite direction. Even though he didn't recognise most of the people involved, it was very easy to see which side he was meant to be on. He started with a few defensive charms but found they had very little effect. He switched to offensive, but the spells seemed to just evaporate through the crowd. He stood his ground as someone seemed to charge at him, only they went straight through him.
Then everything seemed to be jumping about all over the place. There was Fenrir Greyback. His blood chilled at the sight of him, but he had no sooner appeared that he had dissolved into another image. Dead bodies. A boy with a sword. A dragon.
The dragon was real. It looked different, it felt different to the rest of the images. And sure enough, everything else slowly started to fade away. As it did, Remus realised his heart was racing, his palms sweaty, his mouth dry... he let himself flop down to sit on the grass as the adrenaline of a moment ago started to drain away.
