A haunted, demonic mask with glowing red sigils that flicker with an eerie presence. The mask appears cracked and aged, as if it has seen centuries of darkness. The glowing red markings resemble ancient, forbidden scripts or demonic runes, pulsating with a sinister light. The eye sockets are hollow, giving it an emotionless, soulless gaze. The overall design is slightly asymmetric, with carved details that suggest a cursed or supernatural origin.
