A high-quality art_style illustration of a sprawling fantasy castle complex at time_of_day. The sky is deep blue, filled with sparkling stars and a celestial_object positioned in the upper left. The architecture consists of light gray stone walls, featuring exactly 8 prominent cylindrical towers with roof_color conical roofs, and a main rectangular building with a matching pitched roof. window_light_color 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.
