A colossal, ancient tree with bioluminescent bark, its roots stretching deep into a glowing, floating city made entirely of mystical crystals. The sky above is a swirling canvas of geometric constellations, shifting and morphing like an alien language. Time itself bends, and floating islands drift through the scene, suspended by threads of light. Each island is an ecosystem—one with vibrant coral reefs, another with towering ice mountains glittering under a surreal purple sun. A mechanical phoenix with wings made of liquid glass flies across the horizon, leaving a trail of shimmering, fractal patterns that break the very air around it. In the center, a monolithic obelisk, half stone, half liquid metal, stands as a beacon for lost civilizations, while a giant cosmic jellyfish, with lightning-like tendrils, drifts through the void. The scene is bathed in an impossibly vivid color palette, where neon blues, glowing purples, and molten golds collide in surreal harmony.
