A stylized skull relief carved into a dark stone wall, with intense red glowing eyes. The rough, matte surface of the wall blends seamlessly with the skull, its intricate lines and weathered cracks hinting at ancient origins. The red eyes emit an eerie glow, casting faint shadows across the stone. Subtle chisel marks and worn edges give the relief a mystical, timeworn presence, as if guarding forgotten secrets from a lost world.
