<nc-section data-title="Version 1" data-color="red"> Near the stables, a broad-shouldered knight waited beneath a weathered archway. His silver breastplate bore the crest of a rearing lion, and one hand rested lightly upon the pommel of his sword. “You must be Frederick,” he said, studying the young squire with stern gray eyes. “I am Sir Roland. Welcome to the castle—though whether you remain welcome will depend upon how quickly you learn.” Frederick dismounted and bowed. Behind the knight, the horses shifted uneasily in their stalls, as if they too understood the weight of his words. </nc-section> <nc-section data-title="Version 2" data-color="green"> As Frederick guided Thunder toward the stables, a laugh rang out from beside the hayloft. “So this is the new squire!” A knight stepped into view, carrying an armful of tack. His dark hair was streaked with silver, but his smile was warm. “Sir Roland,” he said, dropping the saddle onto a rail and offering Frederick a calloused hand. “You’ve arrived just in time. Thunder needs brushing, the stalls need mucking, and I need someone brave enough to face the cook’s stew.” Frederick smiled despite his nerves and clasped the knight’s hand. </nc-section> <nc-section data-title="Version 3" data-color="blue"> The stable yard lay strangely quiet when Frederick arrived. A lone knight stood among the lengthening shadows, his crimson cloak stirring in the evening wind. A pale scar crossed his face from temple to jaw. “Frederick,” he said before the squire could introduce himself. “I am Sir Roland.” Thunder snorted and backed away. Sir Roland’s gaze shifted toward the darkening northern sky, where a single winged shape passed briefly across the clouds. “You chose a dangerous night to come to this castle,” he murmured. “The dragons have begun to fly again.” </nc-section>
