<nc-section data-title="Version 1" data-color="red"> Near the stables, where the air was thick with the scent of hay and horse sweat, Frederick swung down from Thunder’s back and tried to steady his nerves. Before he could lead the stallion inside, a tall knight stepped from the shadows of the stable doors. His polished mail caught the last red light of sunset, and a deep scar traced one weathered cheek. “You must be Frederick,” the knight said, his voice calm and strong. “I am Sir Roland, master of horse and keeper of discipline in this yard.” Frederick bowed quickly, nearly fumbling Thunder’s reins in his haste. “Yes, sir. I have come to begin my training.” Sir Roland’s stern face softened with the hint of a smile. He reached out and ran a practiced hand along Thunder’s neck, and the great stallion, who had tolerated no stranger on the road, lowered his head without protest. “A good horse,” Sir Roland said. “That tells me something of the rider.” Frederick straightened, uncertain whether to feel proud or afraid. “Come,” said Sir Roland, turning toward the stables. “The castle has little patience for dreamers, but it has some use for boys willing to work. Let us see which sort you are.” </nc-section> <nc-section data-title="Version 2" data-color="green"> Frederick had barely set foot on the cobbled yard when the stable doors creaked open and a broad-shouldered knight emerged, carrying a lantern in one hand. Its golden light fell over a square face, a trimmed beard, and eyes sharp enough to measure a man in a heartbeat. “So,” the knight said, looking Frederick over from boots to brow, “the new squire has arrived at last.” Frederick swallowed and nodded. “Yes, sir.” The knight gave a grunt that might have been approval. “Sir Roland. These stables are under my charge, and until you learn your place in this castle, you’ll do well to listen when I speak.” “Yes, Sir Roland.” Thunder stamped once, and Sir Roland glanced toward the stallion with interest. “Strong beast. Spirited. You’ll tend to him yourself, understand? A careless squire does not stay a squire for long.” Frederick tightened his grip on the reins. “I understand.” For a moment, Sir Roland studied him in silence, as if weighing more than his words. Then he stepped aside and motioned Frederick in. “Good. Bring the horse. Supper can wait. First, I want to see whether you know how to care for what carries you.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> The stable yard was quieter than the castle gate, lit only by the fading sky and the warm glow spilling from the open doors. Frederick led Thunder across the straw-strewn ground, his boots crunching softly, when a knight in a dark blue surcoat approached from between the stalls. He moved with the easy confidence of a man long used to command. Silver touched his temples, though his back was straight and his hand rested on his sword as naturally as another man might rest it on a cane. “Frederick,” he said, and though it was not a question, there was no unkindness in it. Frederick blinked. “Yes, sir.” “I am Sir Roland,” the knight said. “I was told to expect a boy from the western farms. I did not expect one who rides in on a beast like that.” Frederick glanced at Thunder, unsure how to answer. “He has been with me for years.” “Then count yourself fortunate,” Sir Roland replied. He stepped closer, and Thunder snorted, then went still under the knight’s steady gaze. “In this castle, loyalty is rarer than courage, and worth more.” Frederick felt those words settle heavily in his chest. Sir Roland took the reins gently and handed Frederick a stable brush from a nearby hook. “See to your horse. Then come find me in the training yard. If you are to serve here, dawn will not wait for you.” </nc-section>
