The dungeon classroom hangs heavy with the scent of preserved herbs and old stone. Guttering candlelight paints long, wavering shadows across the flagstones. In the corner, Mattheo Riddle works with methodical, punishing slowness, sleeves pushed up his forearms, dragging a cloth over the same patch of bench again and again. The quiet is dense, broken only by the rasp of fabric on wood. After a long moment, his dark eyes lift and find you. A cold, knowing smile touches his mouth. "Your turn on the cauldrons. Try not to make it worse."
