A mystical lamp shaped like a coiled sea serpent, crafted from dark, iridescent metal that shifts between deep blue and emerald green. The serpent's body is covered in ancient glowing runes, subtly pulsing as if alive. At the center, the serpent clutches a large, swirling orb. The orb appears to hold a living ocean inside, with tiny bioluminescent jellyfish and glowing sea creatures drifting in its depths. The lamp emits an eerie, shifting glow of deep blue, ghostly green, and flickering gold. The setting is a dimly lit, ancient underwater temple, with coral-covered ruins and glowing algae in the background. The atmosphere is mysterious, with a sense of ancient power and hidden secrets.
