<nc-section data-title="Version 1" data-color="red"> Near the stables, Frederick dismounted and handed Thunder’s reins to a waiting groom. Before he could take in the bustling courtyard, a broad-shouldered knight in a weathered blue cloak strode toward him. “You must be Frederick,” the man said, extending a gauntleted hand. “I am Sir Roland. Welcome to the castle—and to the beginning of the hardest years of your life.” Frederick clasped his hand and tried not to show his nerves. Sir Roland’s stern face softened into the faintest smile. “Come,” the knight said. “Let us see whether you hold a sword as well as you hold a saddle.” </nc-section> <nc-section data-title="Version 2" data-color="green"> Frederick found Sir Roland leaning against the stable doors, feeding slices of apple to an elderly gray mare. The knight looked nothing like the glorious warriors sung of in taverns. His cloak was muddy, his boots were cracked, and a pale scar crossed his chin. “So,” Sir Roland said without looking up, “the castle has sent me another hopeful boy.” Frederick bowed. “I have come to serve, sir.” At that, Roland turned. His sharp eyes measured Frederick from head to heel. “Good. Pride makes poor armor, but courage can be forged.” He tossed Frederick the last slice of apple. “See to your horse first. A squire who neglects his mount is unworthy of a knight’s trust.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> As Frederick approached the stables, a sudden roar echoed from somewhere beneath the castle. Thunder reared, nearly tearing the reins from his hands. The grooms froze, their faces pale. Only one man remained calm. Sir Roland emerged from the stable shadows in blackened armor, one hand resting upon the pommel of his sword. His gaze lingered on Frederick before shifting toward the distant northern tower, where ravens circled against the crimson sky. “Frederick,” he said gravely. “You have arrived sooner than I expected.” “How do you know my name?” Roland stepped closer and lowered his voice. “Because the creature beneath this castle spoke it three nights ago.” </nc-section>
