Sunlight filtered in through the stained glass windows, throwing beautiful colors over the books and their readers. Sirius Black, though completely bored and uncaring about the things around him, looked up and took notice of the colors around him. He had been staring out of the window, lost in thought, mostly thinking about one girl...He looked up from the school grounds and looked at the students around him. James, Lupin, and Peter, or their nicknames Prongs, Moony, and Wormtail. It had been Sirius, or Padfoot, who thought up these nicknames, but all the friends used them. Wormtail was sitting behind a bookshelf in the library, where they all were, and he was casting Tripping Jinxes into the aisles, sniggering loudly every time somebody tripped. Padfoot only thought this to be mildly funny, but not nearly as much as Wormtail who couldn't breath because of the laughter. Padfoot then looked at Moony, looking pale as always, reading a book named Dark Creatures and Protection against them by Draydur Gnilpik. Sirius couldn't believe that Moony thought that stuff to be interesting. Finally, he turned to the friend next to him, Prongs, who was trying to do Transfiguration homework, but was obviously staring at something across the room. Sirius looked in that direction, and thought his heart would stop beating.
