A terrifying humanoid entity entirely wrapped in decayed cloth and rough burlap sack, bound with rope, with no visible body beneath. Photorealistic, ultra-detailed, hyper-realistic. Sinister cinematic horror tones with muted browns, blacks, and sickly greens. Dim candlelight and shafts of pale light breaking through cracks in the stone ceiling, casting dramatic shadows on ancient coffins, crumbling walls, and dust swirling in the air. Claustrophobic, dreadful ambience.
