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: Sir Roland at the Stables" data-color="red"> By the time Frederick reached the stables, the last light of evening had softened the castle yard into gold and shadow. The air smelled of hay, leather, and warm horses, and the stablehands moved about with practiced haste, carrying buckets and brushing down the mounts returned from patrol. A broad-shouldered knight stood waiting beside the stable doors, his mail shirt half-hidden beneath a weathered cloak. His hair was touched with gray at the temples, and a pale scar crossed one cheek, but there was nothing harsh in his expression. He watched Frederick dismount with the easy patience of a man long accustomed to greeting nervous newcomers. “You must be Frederick,” he said, stepping forward and offering a gloved hand. “Sir Roland of Blackmere. I was told to expect a new squire before sundown.” Frederick took the knight’s hand quickly, trying not to show how stiff and travel-worn he felt. “Yes, sir. I arrived only moments ago.” Sir Roland glanced at the horse, then back at the boy, and a faint smile touched his mouth. “You kept your seat well enough on the road, and your horse isn’t blown or lathered. That tells me you’ve more sense than many boys twice as eager.” He nodded toward the stable. “Come. Your mount will be fed, and you’ll need food yourself before the castle begins to feel less like a giant stone trap.” Frederick let out the breath he had been holding. There was firmness in Sir Roland’s voice, but also warmth, and for the first time since he had seen the towering walls of the castle, the place seemed a little less forbidding. Gathering his cloak, he followed the knight into the stableyard, unaware that this simple welcome would be the first step into a life far stranger than he had imagined. </nc-section> <nc-section data-title="Version 2: The Knight’s Welcome" data-color="green"> Frederick swung down from the saddle near the stables, his boots striking the packed earth with a jolt that ran up his tired legs. Around him, the castle bustled in the fading light. Horses stamped in their stalls, chains rattled, and somewhere nearby a groom laughed before being hushed by a sharper voice. “That will be Frederick, I take it.” The speaker emerged from the stable gloom like a figure carved from old oak and iron. Sir Roland wore no helm, only a dark surcoat over chainmail, and at his hip hung a sword polished from years of use. His gaze was keen, but not unkind. Frederick straightened at once. “Yes, sir.” Sir Roland studied him for a heartbeat, then inclined his head. “Good. You made fair time from the outer road. Not every lad arrives with both courage and horse still intact.” He reached for the reins before Frederick could protest and handed them to a waiting stableboy. “You’ll learn quickly here that a beast should be cared for before pride, and duty before comfort.” Frederick nodded, though his cheeks warmed. “I understand, sir.” “Do you?” Sir Roland asked, though there was humor beneath the question. He rested a hand briefly on Frederick’s shoulder, solid and steady. “Then perhaps you’ll do well at this castle after all. Come with me. The master-at-arms can wait until morning. Tonight, you need supper, a bed, and the good sense not to wander where the old towers lean.” Frederick glanced toward the looming battlements, their high windows already darkening against the sky. A strange thrill stirred in him—part fear, part wonder. With Sir Roland leading him past the lantern-lit stable doors, the castle no longer seemed only a fortress. It felt like the threshold of a story beginning to open. </nc-section> <nc-section data-title="Version 3: First Meeting with Sir Roland" data-color="blue"> The stableyard was quieter than the gatehouse but no less alive. Lanterns had been lit beneath the eaves, their amber light falling over rows of stalls and piles of fresh straw. Frederick had barely loosened his grip on the reins when a knight stepped out from beside the watering trough. He was tall, with a soldier’s bearing and a face marked by years of sun and battle. Yet his eyes were calm, and when he spoke, his voice carried the steadiness of someone used to command. “Frederick,” he said. “Welcome to the castle.” The boy blinked in surprise. “You know my name, sir?” Sir Roland gave a short nod. “Word travels faster than horses inside these walls. I am Sir Roland. I oversee the training yard when the captain is away, and it seems I have been entrusted with seeing that you do not lose yourself before your first lesson.” A stablehand came to take Frederick’s horse, but Frederick hesitated, giving the animal’s neck one last pat. Sir Roland noticed. “You care for your mount,” the knight said. “Good. Remember that. A man’s true nature is often shown first by how he treats those beneath his power.” Frederick looked up at him, uncertain whether this was praise or testing. “I’ll remember, sir.” Sir Roland’s stern expression eased. “See that you do. The castle has need of squires who listen.” He motioned toward a side door leading from the stables into the inner ward. “Come. I’ll show you where you’ll sleep, and on the way I may tell you which knights to avoid when they’ve lost at dice.” Despite his weariness, Frederick smiled. He followed Sir Roland beneath the lantern glow, listening to the murmur of horses behind him and the distant clang of steel somewhere deeper in the castle. The road had ended, but something greater had begun. </nc-section>
