My horse, a majestic stallion named Thunder, galloped across the open field. The wind whipped through my hair as I rode towards the castle gates. The sun was setting, casting a warm glow over the stone walls. I could see the banners of the kingdom fluttering in the breeze.

<nc-section data-title="Version 1" data-color="red"> Near the stables, Frederick dismounted Thunder and handed the reins to a stable boy. Before he could take more than a few steps, a broad-shouldered knight emerged from the shadows. His silvered beard framed a stern face, and a scar ran from his left temple to the corner of his mouth. “Frederick?” the knight asked. “Yes, sir.” “I am Sir Roland, captain of the castle guard.” His gaze moved from Frederick’s travel-stained cloak to the sword at his hip. “You are late.” Frederick swallowed. “The road was longer than I expected, Sir Roland.” “Then you had best learn to expect the unexpected.” Roland turned toward the stables. “Come. Dawn comes early here, and tomorrow you begin learning whether you are truly fit to serve a knight.” As Frederick followed, Thunder suddenly snorted and stamped. From somewhere beyond the castle walls came a low, distant growl. </nc-section> <nc-section data-title="Version 2" data-color="green"> Frederick found the stables glowing with lantern light and smelling of hay, leather, and warm horses. A knight in a green-plumed helm stood beside the largest stall, speaking softly to a restless warhorse. When he saw Frederick, the knight smiled. “You must be the new squire.” Frederick bowed quickly. “Frederick of Ashford, at your service.” “Sir Roland.” The knight clasped his forearm in greeting. His grip was firm but friendly. “You have arrived on an interesting night. The castle has been quiet for three months, and now the ravens are flying in from the north.” “What news do they bring?” Roland’s smile faded. “None that a young squire need worry about yet. See to your horse, eat what you can, and keep your eyes open.” A sharp cry echoed from the battlements. Every horse in the stable reared against its tether. Sir Roland reached for his sword. “On second thought,” he said, “you may begin your training tonight.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> The stable doors creaked open as Frederick led Thunder inside. A tall knight waited beneath the rafters, his blue cloak falling over polished armor. He carried no helmet, and his weathered face held the patient calm of someone who had survived many battles. “Frederick,” he said. “I am Sir Roland.” Frederick bowed. “It is an honor, sir.” “That remains to be seen.” Roland glanced at Thunder, who lowered his head and nudged the knight’s shoulder. “At least your horse has better manners than most boys who arrive here.” For the first time since leaving home, Frederick laughed. Sir Roland gestured toward a narrow room above the stalls. “That will be your bedchamber. You will rise before sunrise, polish the armor, tend the horses, and train until your arms can scarcely lift a spoon.” Frederick looked toward the castle, where the last light faded from the towers. “And if I fail?” Roland studied him in silence. Then, from high above, a strange blue glow flickered across the clouds. “Then,” said the knight, “we will discover what is waiting beyond the mountains.” </nc-section>
