Aerial drone shot of a massive three-tier fortified stone citadel built into a rugged mountain. The lower tier features heavy defensive walls, iron gates, and stone barracks. The middle tier has defensive walls, a small gate, and stone houses. The upper tier is carved directly into the mountainside, with a majestic gothic castle partially embedded inside the living rock. High angle bird's-eye view showing the entire circular perimeter. Dramatic sunset lighting, misty valleys below, photorealistic textures, Unreal Engine 5 style.
