A chilling creature resembling a giant spider with a sleek, dark exoskeleton and large, glimmering reddish eyes, its many legs lined with fine, wispy hairs. The setting is a dimly lit, echoing cave, with stalactites hanging ominously from the ceiling. An open wooden chest overflowing with glistening emeralds rests upon the rocky ground, casting a verdant glow across the cavern. The scene is rendered in intricate detail, capturing the creature's menacing form and the chest's dazzling contents in a fantastical, horror-inspired cinematic style in vivid 4k resolution.
