The tower is geometric and metallic with glowing blue plasma veins running vertically, converging toward a radiant crystal core at its peak. Surrounding the tower, the city extends outward in concentric layouts — high-density blocks of futuristic skyscrapers, each with metallic textures, glass reflections, and sunlight scattering realistically across their surfaces.
