<nc-section data-title="Version 1" data-color="red"> Near the stables, Frederick reined Thunder to a halt. A broad-shouldered knight in a weatherworn crimson cloak waited beside the open doors, one hand resting upon the pommel of his sword. “You must be Frederick,” he said, studying the young squire with stern gray eyes. “I am Sir Roland. Tend your horse well, then report to the training yard. At this castle, duty begins before comfort.” Frederick swallowed his nerves and dismounted. “Yes, sir.” The knight’s severe expression softened by the smallest degree. “Good. At least you know how to answer.” </nc-section> <nc-section data-title="Version 2" data-color="green"> As Frederick approached the stables, the scent of hay and oiled leather mingled with the cool evening air. A knight emerged from beneath the timbered arch, carrying two apples in one gloved hand. “Thunder, is it?” the man asked, offering one to the stallion. “Fine name. Let us hope he deserves it.” Frederick smiled despite himself. “He does, sir.” The knight tossed him the second apple. “Sir Roland. I oversee the squires—and occasionally rescue them from their own foolishness. Welcome to the castle, Frederick.” For the first time since passing through the gates, Frederick felt he might belong there. </nc-section> <nc-section data-title="Version 3" data-color="blue"> Frederick had nearly reached the stables when a tall knight stepped from the shadows. His armor bore old scratches, and the silver dragon engraved upon his breastplate seemed to gleam in the dying light. “Frederick,” he said, as though he had been expecting him. “I am Sir Roland.” Before Frederick could reply, Thunder shied and stamped the earth. Somewhere inside the stable, something answered with a low, rumbling growl. Sir Roland’s hand moved to his sword. “Take your horse and stand behind me.” Frederick obeyed, staring into the darkness beyond the doors. His first night at the castle had suddenly become far more dangerous than he had imagined. </nc-section>
