<nc-section data-title="Version 1: Sir Roland’s Welcome" data-color="red"> At the stables, the air smelled of warm hay and iron-shod hooves. I dismounted and hitched Thunder by the slack of the reins, but before I could settle my pack, a voice cut through the clatter. “Easy there, lad. New boots, new duties, and no sense of falling yet.” Sir Roland emerged from the shadow of a grooming shed like a man carved out of disciplined might. His armor was scuffed in honest places, polished in others where he seemed to remember every battle that had mattered. A chain of keys jingled at his belt, and his gaze—sharp as a hawk’s—traced the way I moved. “Frederick,” he said, as though the name had already been tested. “You’re late enough that the horses have started to wonder if you’ve forgotten them.” He hooked a thumb toward the stall where Thunder had been led. “But you’re early enough that you haven’t ruined your first day.” I swallowed, feeling suddenly younger than my age. “Sir Roland. I— I arrived at the gate as soon as I could.” “That’s not an answer worth boasting about,” he replied, and yet the corner of his mouth lifted. “Still, it’s the only one you can give. Come—let’s see if you can hold a lance without fidgeting like a nervous fish.” He clapped my shoulder once, hard enough to set my bones straight. “First lesson: respect the stable, and the stable will respect you.” </nc-section> <nc-section data-title="Version 2: The Knight Tests the Hands" data-color="green"> Near the stables, the world quieted into softer sounds—brush on leather, water in buckets, the steady breath of horses that had learned not to fear men. I kept my eyes forward as I approached, trying not to look like I didn’t belong in my own skin. A polished gauntlet stopped me before I could reach the tack room. “Frederick.” Sir Roland’s voice was calm, but it carried authority the way steel carried heat. He wore his insignia plainly, without flourish, and that made it feel heavier. The local knight looked me over—not for my clothes, not for my speech, but for the posture of my shoulders and the impatience in my fingers. “Your master sent you,” he said, “which means you must already have some measure of worth. But worth is not the same as readiness.” I tried to salute. My arm rose a beat too slowly, like a door in a stiff hinge. Sir Roland’s eyes flicked to the mistake and then away, mercifully. “Good,” he murmured. “You noticed. That’s the first step. The second is learning not to pretend you didn’t.” He guided me toward Thunder’s stall and nodded at my hands. “Tell me—have you ever braided a horse’s mane?” “Once,” I admitted. “When I was younger.” “Once is a start,” he said. “But today you’ll do it properly. If you can’t care for what’s living and breathing beside you, you’ll never manage what’s breathing and biting on the battlefield.” Then, softer: “Show me you can listen, Frederick. Horses speak in patience. Knights must, too.” </nc-section> <nc-section data-title="Version 3: Sparks in the Courtyard" data-color="blue"> The stables rose ahead of me like a fortress of wood and stone, built to outlast weather and men alike. Inside, lanternlight gilded everything—the grain sacks, the polished bits of tack, the gleam of a bridle hung just so. I was halfway to the grooming aisle when a shadow fell across my path. Sir Roland stood there as if he’d been waiting for my footsteps. His surcoat was dark with use, his sword belt heavy with purpose, and his expression held the friendly severity of someone who’d seen too many boys mistake confidence for courage. “Frederick,” he said, pronouncing it like a command and a test in the same breath. “You’ve come to learn, yes?” “Yes, Sir Roland,” I answered quickly, then slowed myself, trying to sound steadier than I felt. He gestured toward the courtyard beyond the stable doors, where the yard was scrubbed and ready for instruction. “Then we begin where all lessons begin—at your station. You’ll speak with the stablemaster, you’ll learn the names of the horses, and you’ll keep your hands busy before your mind wanders.” As he spoke, one of the older riders tugged a cart wheel into place, and the sound of metal against stone rang through the air like a warning bell. Sir Roland’s gaze sharpened in that moment, as if he could hear futures breaking. “Come,” he said, and his voice turned brisk. “I’ll show you how a knight approaches work without rushing it—and how he steps aside before a kick teaches him humility.” He took my sleeve, not unkindly, and steered me closer to the stalls. “First rule, squire: learn respect in small moments. That is where the dragon’s lesson will start, whether you know it yet or not.” </nc-section>
