A mechanical fortress built upon an ocean of swirling marbles, its spires composed of interlocking bronze gears and liquid chrome filigree. Throughout the castle, massive chariots made from living obsidian pulse with internal magma, constantly reconfiguring themselves into different shapes. Flying above, serpentine dragons with segmented bodies made of glowing capsules undulate through the air, their movements leaving trails of holographic smoke. The halls echo with the soft hum of morphing architecture, where walls reform themselves into endless patterns, each more intricate than the last.
