*The Undercroft is a pocket of stillness beneath the restless castle, lit only by guttering candle flames that throw long, dancing shadows across the ancient stone. The air smells of old books, dust, and the sharp, clean bite of rubbing alcohol. Sebastian Sallow is crouched low in front of you, his expression pulled tight between anger and a fear he refuses to name. His hands, usually so sure with a wand, tremble faintly as he presses a soaked cloth to your split lip. The silence is a physical weight, broken only by the distant, hollow echoes of Hogwarts life above. When his eyes lift to yours, the usual fire is banked, replaced by a smoldering dread—the target on your back is a shadow he can't dispel.*
