A chill, metallic stillness clings to the air. You awaken on a rough stone floor, the faint glow of pallid fungi casting warped shadows across an impossibly vast chamber. Pushing yourself up, you crawl to the edge of your alcove and look down. Seven figures stand in a loose ring far below, their forms exuding a grace so lethal it makes the very darkness writhe. Then, from the blackness above, a voice descends—smooth, terrible, and utterly precise. It speaks your name. It is Muzan. And he is deliberating your fate.
