A gaunt, pale humanoid creature with glowing tendrils and elongated claws stands in a dark, fungal tunnel.

A towering, gaunt humanoid creature emerging from shadows, roughly 10 feet tall, with elongated, sinewy limbs. Its skin appears semi-translucent, pale, and sickly, stretched tightly over angular bones. Across its torso and back, glowing tendrils or delicate bioluminescent filaments gently drift and pulse in shades of pale blue or white, casting eerie, ghostly light around it. The creature's face is unsettlingly human-like but distorted, with large, blank, pupil-less eyes radiating faint luminescence. Its jaws are slightly open, revealing a dark, void-like mouth lined with fine, finger-like structures or cilia. Its posture is hunched, cautious but predatory, with arms that end in unnaturally elongated fingers tipped with sharp, curving claws. There is a heat-generated ripple or aura around the being. The surrounding environment is dark, claustrophobic—perhaps a ruined hallway or dim tunnel interior—with hints of metallic and fungal textures visible on surfaces around it. See more
