Hollow Mourn A ghostly alien with a semi-transparent body resembling stretched porcelain. Its head is smooth and featureless except for a wide, permanent mouth carved into a silent scream. Faint blue light flickers inside its hollow body, like a flame struggling to burn. Its limbs are long and jointless, tapering into smoky trails instead of hands. Thin, ribbon-like appendages float around it like drifting cloth. When it moves, it leaves behind a faint afterimage, and its presence seems to drain warmth from the air.
