Moonlit Fantasy Castle Mystery

A high-quality {argument name="art style" default="anime background art"} illustration of a sprawling fantasy castle complex at {argument name="time of day" default="night"}. The sky is deep blue, filled with sparkling stars and a {argument name="celestial object" default="large full moon"} positioned in the upper left. The architecture consists of light gray stone walls, featuring exactly 8 prominent cylindrical towers with {argument name="roof color" default="blue"} conical roofs, and a main rectangular building with a matching pitched roof. {argument name="window light color" default="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.
