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"> The local knight, Sir Roland, greets Frederick near the stables. He did not offer a smile. The tall man in polished steel stood with his arms folded, watching Frederick fumble with Thunder's reins as the stallion stamped and snorted in the straw. "Boy," Sir Roland said, his voice low and hard. "You have arrived two hours late, and your horse is lathered like you rode him to death. If this is how you care for a beast in your charge, you will not last a week under my command." Frederick straightened at once, heat rising to his cheeks. "Forgive me, Sir Roland. The road from the village—" "The road is the same for every squire who comes here," Roland interrupted. He stepped forward and ran a gauntleted hand down Thunder's neck, inspecting the animal with a practiced eye. "He is a fine horse. Strong. That means you must be stronger. Now take him to his stall, brush him down, and feed him. Then you will report to the armory. And do not keep me waiting again." </nc-section> <nc-section data-title="Version 2" data-color="green"> The local knight, Sir Roland, greets Frederick near the stables. "Ah, so you must be Frederick!" boomed a cheerful voice. Frederick turned from tending to Thunder to see a broad knight with a round belly, a bushy red beard, and a helm tucked carelessly under one arm. Sir Roland grinned so widely that Frederick wondered if he ever frowned at all. "Welcome to the castle, lad! And who is this splendid fellow?" Roland clapped Thunder on the flank, making the stallion blow through his nostrils. "Fine animal. Fine name, too, I'll wager. Let me guess — Storm? Lightning? No? Thunder, is it?" Frederick laughed, relief loosening his shoulders. "Yes, sir. Thunder." "Ha! A horse after my own heart. Come, I'll show you where to stable him, and then we'll get you something to eat before the steward decides you're too skinny to be of any use. Training can wait a little. A full stomach never can." </nc-section> <nc-section data-title="Version 3" data-color="blue"> The local knight, Sir Roland, greets Frederick near the stables. He was already there when Frederick led Thunder through the great wooden gates, as if he had been waiting in the shadows between the stalls all evening. Sir Roland wore no bright colors and made no sound, though his armor caught the last blue light of dusk. "Frederick of the valley," he said quietly. It was not a greeting so much as a recognition. "You rode hard." Frederick nodded, uneasy. Above them, somewhere beyond the castle towers, came a faint, distant cry — not a hawk, not a horn. Thunder tossed his head and pawed the ground. Roland did not look up. "The last dragon grows restless in the mountains," he murmured. "It can sense a new squire's horse, I think. Or perhaps it senses you." He turned at last, and his eyes were grave. "Stable your horse. Rest tonight. Tomorrow, you will learn to hold a sword. You may need it sooner than you think." </nc-section>
