<nc-section data-title="Version 1" data-color="red"> Near the stables, I drew Thunder to a halt. A broad-shouldered knight in a weathered blue surcoat stepped from beneath the eaves, one gloved hand resting on the pommel of his sword. “You must be Frederick,” he said, studying me with stern gray eyes. “I am Sir Roland. If you have come to become a knight, leave your pride at the gate and bring your courage with you.” He took Thunder’s reins and gave the stallion an approving nod. “Come. Your training begins at dawn.” </nc-section> <nc-section data-title="Version 2" data-color="green"> The stable yard smelled of hay, leather, and woodsmoke. Before Frederick could dismount, a tall knight with a scar along his jaw approached and steadied the horse by its bridle. “Easy there,” the man murmured to Thunder. Then he looked up at Frederick, and a faint smile softened his severe face. “Welcome to the castle. I am Sir Roland, and I have been given the questionable honor of making a warrior out of you.” Frederick climbed down, uncertain whether the knight was jesting. Sir Roland’s smile vanished. “First lesson: a knight must know when danger is hidden behind friendly words.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> Frederick reached the stables as the last light faded behind the castle towers. A lone knight waited beside the open doors, his silver armor reflecting the crimson sky. An old dragon was engraved upon his breastplate. “Frederick,” he said before the squire could introduce himself. “You are later than I expected.” “I rode as swiftly as I could, sir.” The knight glanced at Thunder’s foam-flecked flanks. “So I see.” He extended his hand. “Sir Roland. Your master, until you earn the right to choose your own path.” From somewhere deep within the castle came a low, distant rumble. Thunder shied, and Sir Roland’s expression darkened. “It appears,” he said, turning toward the towers, “that your arrival has awakened something.” </nc-section>
