<nc-section data-title="Version 1: Sir Roland at the Stables" data-color="red"> The castle’s stables came into view like a fortress of timber and iron. Straw-smell and horse-sweat mingled in the air, and the restless stamping of hooves sounded like distant thunder. As Thunder snorted, I swung down from the saddle and pulled the reins loose, letting my stallion settle beside the other mounts. A knight waited near the tack room—tall, broad-shouldered, and armored in polished plate that caught the last light of day. His crest, a silver falcon half-spread, glimmered above the shoulder guards. When he stepped forward, his boots rang once against the packed earth, as if the ground itself were taking attendance. “Frederick,” he said, and my name sounded less like a question than a sentence. “You’ve come on time.” Sir Roland’s gaze swept over me—scarf, boots, hands—pausing at my sword arm with a quick, practiced assessment. “You’ll find the castle has its own rules. The stable yards are where lessons begin. Not with speeches.” Before I could answer, he gestured toward the nearest stall. “Warm the horses, check their tack, and learn their moods. A rider who ignores the small signs rides blind.” I nodded, suddenly eager and terrified all at once. I had dreamed of grand duels and heroic quests, yet here stood a man who treated horsehair and buckles as if they were sacred magic. Sir Roland leaned closer, voice low enough to stay between us and the steady breathing of the beasts. “And one more thing,” he added. “If you hear the bells ring thrice after dusk, do not go looking for noise. That’s when the castle forgets to be safe.” </nc-section> <nc-section data-title="Version 2: The Knight’s Test" data-color="green"> The stables were warmer than the yard outside, thick with the soft steam of living breath and the sweet bite of oats. I led Thunder toward a row of dark stalls, but I didn’t get far before a voice called from behind the grooming shed. “You there. Squire.” I turned to find Sir Roland standing with the ease of a man who had mastered both armor and patience. His helm hung under one arm, the metal casting a faint shadow across his stern features. There was something weathered in his eyes—battle-scarred, yes, but also tired of fools. “Sir Roland,” I managed, bowing too quickly. He made a small sound that might have been approval—or might simply have meant he’d heard sharper greetings in worse places. “You look ready to work,” he said, and then, without waiting for my reply, he pointed at my hands. “Let’s see if you are.” He handed me a leather strap slick with oil and dust. “This buckle’s been forced twice. Fix it, and if you can’t, tell me why. Do not hide behind excuses. The horses feel lies.” I knelt beside the tack and set to work, tightening and loosening with careful fingers, reading the grain of the leather the way I’d learned to read a map. Sir Roland watched silently, as if my clumsiness or skill would reveal something more important than the buckle itself. When I finally secured it, the strap settled with a satisfying click. “There,” he said. “Now take Thunder’s bridle and walk him at a measured pace. No rushing. No smacking. If he spooks, you calm him—not the other way around.” Only then did he offer a half-smile, sharp as a blade. “Welcome to your training, Frederick. The castle begins teaching the moment you stop trying to impress it.” </nc-section> <nc-section data-title="Version 3: Banners and Warnings" data-color="blue"> Thunder’s hooves slowed as we reached the stables, drawn by the low chorus of neighing and the rhythmic scrape of curry combs. I hadn’t realized how loud my own arrival had been until the yard fell quiet for a heartbeat—until I saw him. Sir Roland approached from between two posts, armor catching the firelight that had begun to wake inside the stable lanterns. His cloak was dusted with the pale grit of travel, and his sword—still sheathed—seemed to carry its own gravity even at rest. “So this is Frederick,” he said, voice steady, the kind that could command a hall without raising its volume. “They sent you to learn, not to daydream.” “I came to learn, Sir Roland,” I answered, trying to keep my excitement from shaking my words. He studied me like a man checking the seams of a shield. Then he turned slightly, indicating the stable yard beyond. “You’ll hear the castle long before you see the people. Listen. There’s order here—until it isn’t.” He motioned for me to follow, toward the grooming stations lined neatly as if they’d been measured by a master’s compass. A stableboy hurried past with a sack of grain; somewhere deeper, a mare whickered anxiously. Sir Roland raised a hand, stopping the boy with a glance. “Fear travels faster than sound,” he murmured to me. “That mare—she smells something unfamiliar.” As I stepped closer, I felt it too: a faint, cold tang on the air, like rain that had never touched the ground. Sir Roland’s eyes narrowed. “Not today,” he said, though he didn’t specify what “today” meant. “But keep your eyes open. Training isn’t only for your hands. It’s for your judgment.” He tapped the side of my scabbard lightly. “You’ll handle steel soon enough. For now, start with care—horses, straps, lanterns, doors. Everything that can save you has already taught someone how to survive.” </nc-section>
