• The city is concentrated in one direction, surrounded by wooded hills and water. Its appearance is inspired by Thessia; geography and buildings are concept imagery, not established setting canon.
• The app uses this texture for the distant background and material reflections. The city faces the throne end of the hall. This is an LDR image, not a calibrated HDR lighting capture; a separate directional light supplies the sun.

Exact generation prompt

Use case: stylized-concept. Asset type: seamless equirectangular environment texture for a Three.js skybox, 2:1 aspect ratio. A serene, sunlit view from the outskirts of a futuristic garden city on Sylir. In ONE direction, grouped around the horizontal center of this panorama, show an impressive skyline inspired by Thessia and Asari architecture in Mass Effect: elegant ivory and silver towers with sweeping curved profiles, graceful pointed crowns, flowing terraces and subtle blue glazing, nestled among green parks. Make this one concentrated city occupy about a quarter of the panorama's width. Its tallest towers rise clearly above the horizon. The remaining three quarters of the panorama look across quiet distant wooded landscape and low hills, without additional cities. The camera is near ground level, not flying above clouds. A pale blue daytime sky with soft white clouds dominates the upper hemisphere, with warm high sunlight and gentle atmospheric haze. Refined realistic architectural visualization, natural colors. Technical composition: a complete 360 by 180 degree spherical panorama in latitude-longitude projection, ideally 3072 by 1536 pixels. Level horizon exactly halfway down the image, sky above, quiet distant green landscape below. Left and right edges connect seamlessly; top and bottom edges are quiet continuous polar regions. No foreground objects, nearby buildings, palace interior, canopy, people, text, panels, or borders.
