Underwater Glacial Oasis

First-person view of a vast, open space within an underwater cave. The cavern is dimly lit by bioluminescent algae scattered across the high, jagged ceiling, casting a faint, greenish-blue glow. The uneven walls stretch outward, creating an expansive, dome-like area, while the echoes of dripping water fill the air. At the center of the cavern stands a solitary table, appearing as if carved naturally from stone. Its surface is rough yet flat enough to hold items. Resting on the table are an oxygen tank, its metallic surface glinting faintly in the low light, and a piece of paper, edges slightly curled from the damp atmosphere. The scene carries an eerie stillness, the objects on the table standing out against the raw, rugged environment, suggesting their purposeful placement in this desolate yet intriguing space.
