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="Chapter 1: A Knight’s Welcome" data-color="red"> Frederick slowed Thunder to a gentle walk as he neared the row of polished stalls. Before he could dismount, a tall figure in gleaming plate armor strode forward, auburn plume bobbing atop his helm. “Welcome to Castle Aelorn, young squire,” the knight rumbled, extending a gauntleted hand. Frederick slid from the saddle and grasped that hand, surprised by its firm, reassuring grip. “I am Sir Roland of Blackwood Keep,” the knight continued, letting his visor click open to reveal a kindly face. “Your training begins at first light. Until then, let me show you where supper’s served.” With a courteous bow, Sir Roland led Frederick toward the lantern-lit courtyard, the faint clink of armor echoing in the still evening air. </nc-section> <nc-section data-title="Chapter 1: The Knight’s Salute" data-color="green"> As Frederick guided Thunder between the stalls, footsteps approached on the cobblestones. A broad-shouldered knight emerged, sword belted at his hip and a bright green sash fluttering from his pauldron. “You must be the new squire,” he said warmly, offering a crisp salute. Frederick returned the gesture, heart thudding with pride. “I’m Sir Roland,” the knight introduced himself, grinning. “Your horse looks well cared for—Thunder suits you.” He patted the stallion’s neck before motioning Frederick toward the tack room. “Come, let me show you your quarters and introduce you to the armorer. You’ll need every advantage if you hope to sit at our side one day.” </nc-section> <nc-section data-title="Chapter 1: Under Watchful Eyes" data-color="blue"> Frederick barely had time to gather the reins when a shadow fell across the stable door. He looked up to see Sir Roland, his armor tinted blue by the torchlight, standing with arms folded. “So you’re the boy the captain spoke of,” the knight said, voice low but firm. Frederick bowed, offering his hand. Sir Roland studied him for a long moment before nodding. “I’ll be the first to test your mettle,” he warned, then gestured toward a training dummy at the yard’s edge. “Show me your best strike tomorrow at dawn. Fail, and you’ll discover that chivalry alone won’t carry a sword arm.” With that, the knight vanished into the darkness, leaving Frederick both unsettled and determined to prove himself. </nc-section>
