<nc-section data-title="Version 1: A Stern Welcome" data-color="red"> The clatter of hooves on cobblestones faded as I reined Thunder to a halt in the stable yard. A tall knight in polished steel armor stood waiting, his arms crossed. His scarred face held no warmth. "You are Frederick, the squire from the lowlands?" He did not wait for my answer. "I am Sir Roland. Your training begins at dawn. Do not be late, boy." He turned and strode away without another word, leaving me in the shadow of the castle. </nc-section> <nc-section data-title="Version 2: A Warm Introduction" data-color="green"> I slid from Thunder's saddle as a cheerful voice rang out. "Well met, young Frederick! I am Sir Roland." The knight approached with a broad smile, his blonde hair tousled and his surcoat slightly dusty from a day's training. He clasped my hand firmly. "Good timing—I was just about to tend to my own mount. Let me show you the stables and find a proper stall for your fine horse. The castle can wait; a squire's bond with his steed comes first." His easy manner put me at ease at once. </nc-section> <nc-section data-color="blue" data-title="Version 3: A Mysterious Greeting"> The stable yard was quiet save for the soft nickering of horses. A knight emerged from the shadow of an archway, his armor dark and unadorned. His gaze was piercing, almost unnerving. "You are Frederick," he said, his voice low like distant thunder. "I am Roland. I have been expecting you." He offered no smile, but his eyes held a glint of curiosity. "There is more to your coming than you know. But first, let us see to your horse. The castle has ears, and the walls have shadows." He turned, gesturing for me to follow. </nc-section>
