A vast citadel of shifting colors rises from a sprawling, maze-like canyon, its translucent walls resembling liquid opal. The labyrinth is alive with glowing plants that emit soft hues of teal, magenta, and amber. Above, a surreal sky shifts between day and night, bathing the structure in alternating waves of golden sunlight and shimmering starlight. Cascading waterfalls of radiant light spill into the canyon, creating pools that pulse like beating hearts. Ethereal tendrils of mist weave through the maze, blurring the lines between structure and nature.
