Ancient abyssal stone guardian monster in an underwater city

A creature of barnacle-encrusted stone, bioluminescent algae, and eyes of ancient abyssal creatures. Corroded brass diving bells, intricate pressure gauges, and slow-moving hydraulic limbs are integrated into it. Ethereal currents of deep-sea magic, faint, hypnotic whispers, and glowing abyssal runes emanate from it. It guards forgotten underwater cities, communicating through telepathic whispers. In the style of Royo, Vallejo, Frazetta, Bell, with dramatic lighting, rich oil texture, 8K, Artstation.
