<nc-section data-title="Version 1" data-color="red"> Sir Roland stood near the stables with his arms folded across his mail-clad chest, a tall figure with a weathered face and a stern brow that softened when he saw Frederick approach. “You must be the new squire,” he said, his voice deep but not unkind. Behind him, the stablehands moved about with pitchforks and buckets, while the scent of hay and horse sweat drifted through the cool evening air. Frederick straightened at once, clutching his satchel as Sir Roland gave a short nod. “If you are to serve here, boy, you will learn quickly that a knight’s strength begins with discipline. Come—let me see how you carry yourself.” </nc-section> <nc-section data-title="Version 2" data-color="green"> Near the stables, Sir Roland was easy to spot, for he wore his polished breastplate even after the day’s duties, as though the armor were part of his very skin. He lifted one gloved hand in greeting when Frederick drew near. “Ah, Frederick,” he said, as if they were old acquaintances rather than strangers. “I had heard the castle was expecting a new squire.” A faint smile touched his mouth as a chestnut mare stamped and snorted behind him. “You’ve arrived at a fine time. The horses are restless, the halls are crowded, and the training yard is never quiet. If you can keep your wits among all that, you may do well here.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> Frederick found Sir Roland beside the stables, where the knight was speaking quietly to a groom and checking the tack with practiced hands. When he noticed the boy, Roland turned and bowed his head in a courteous, almost fatherly way. “You must be Frederick,” he said. “I am Sir Roland of the western watch, and I welcome you to the castle.” The stableyard was alive with the clatter of hooves and the murmur of servants, yet Roland’s presence gave the place a sense of order. He studied Frederick for a heartbeat, then smiled. “Come, let us begin with something simple. If you are to serve a knight, you must first know how a knight thinks.” </nc-section>
