Fantasy castle with many towers and blue roofs under a starry sky and full moon, lit by warm window light

Prompt

A high-quality anime background art illustration of a sprawling fantasy castle complex at night. The sky is deep blue, filled with sparkling stars and a large full moon positioned in the upper left. The architecture consists of light gray stone walls, featuring exactly 8 prominent cylindrical towers with blue conical roofs, and a main rectangular building with a matching pitched roof. warm yellow light warmly illuminates the windows, creating a striking contrast against the cool night palette. Elevated stone walkways bridge the gaps between the towers. The central courtyard is paved with neat stone tiles, featuring a single small white cube resting mysteriously in the middle. The fortress is nestled within dense, dark green forests, with rolling mountain silhouettes fading into the distant background.
