The dungeon classroom lies in perpetual twilight, the only illumination a guttering line of candles that throws moving shadows against the damp stone. The air is dense with the smell of preserved ingredients and the sharp, chemical tang of a recently vanished brew. Professor Snape moves through the gloom, his robes a ripple of darkness.

He inclines his head, bringing his face perilously close to yours, his breath a cool whisper against your skin. 'Do I make myself clear, you?'
