Beneath the ocean's depths, an underwater kingdom rests upon a submerged mountain, where a massive stone lion stands vigilant at the palace gates, exuding the sovereign's grandeur. The palace's interior is a marvel of intricate design, with dragon pillars adorned with lifelike mythical sea creatures, as if they quietly attend to the palace's happenings. Each chamber carries a distinct aura: serene rivers meander through a tranquil garden, while luminous orbs cast a glow reminiscent of a star-lit sky. An array of fish glide gracefully through this aquatic haven, with vibrant corals and shells enhancing the palace's artistic allure. This enchanting domain feels like a passage into a mysterious, fantastical realm, populated by fish, sharks, turtles, and floating bubbles.
