On Snape's other side was an empty seat, which Harry guessed was Professor McGonagall's. Next to it, and in the very center of the table, sat Professor Dumbledore, the headmaster, his sweeping silver hair and beard shining in the candlelight, his magnificent deep green robes embroidered with many stars and moons. The tips of Dumbledore's long, thin fingers were together and he was resting his chin upon them, staring up at the ceiling through his half-moon spectacles as though lost in thought. Harry glanced up at the ceiling too. It was enchanted to look like the sky outside, and he had never seen it look this stormy. Black and purple clouds were swirling across it, and as another thunderclap sounded outside, a fork of lightning flashed across it.
