A majestic armored knight riding a powerful black horse through a golden autumn field. The knight is clad in full medieval plate armor with a polished metal finish, a closed helmet hiding their face, and a flowing dark cape draped behind. The horse, well-muscled and adorned with ornate leather reins and metal-plated tack, gallops gracefully, its mane and tail flowing with motion. The setting is a breathtaking open landscape, with rolling hills and scattered trees in the distance, bathed in warm golden light. The sky is filled with soft, fluffy clouds, creating a dreamy yet cinematic atmosphere. The foreground is rich with autumn flowers and orange maple leaves, swaying gently in the breeze. The scene evokes a sense of mystery, power, and medieval grandeur.
