A humanoid figure with iridescent blue-green skin and long, flowing silver hair sits cross-legged on the ocean floor, surrounded by a sprawling underwater city of crystalline structures that refract and reflect the soft blue glow emanating from the buildings, the figure's eyes closed as they focus on the telepathic network of a crystal skull cradled in their lap, the skull pulsing with a soft, ethereal light that resonates with the bioluminescent energy of the city, schools of glowing fish darting among the ancient statues that line the city's central square, their shimmering scales catching the light and sending shafts of glittering color through the water, the statues themselves covered in glowing, rainbow-hued coral and anemones that wave gently in the current, the figure's hands resting lightly on the skull as they connect with the network, their face serene and intent, the water around them filled with a kaleidoscope of marine life, from giant, slow-moving jellyfish to tiny, darting shrimp, all moving in harmony with the pulsing energy of the city.
