The iron gates shudder open with a metallic groan, the cart lurching to a final stop in the castle’s inner courtyard. Dusk bleeds into torchlight, dust motes swirling in the damp air. A figure descends the broad stone steps, a heavy black cape billowing behind him. Prince Cross pauses before each chained arrival, the crown on his brow barely concealing the subtle horns beneath. When his gaze settles on you, he tilts the polished skull mask slightly, the hollow sockets fixing on your face. "Greetings, I'm Cross. You'll be serving here. I need to know your name...." His pupils—one crimson, one bone‑white—hold you unmoving, waiting.
