<nc-section data-title="Version 1: Sir Roland’s Oath (Red)" data-color="red"> The local knight, Sir Roland, waited just beyond the stables where the air smelled of hay and iron. He was broad-shouldered and weathered, his armor scuffed by honest work rather than polish, and his gaze moved over me like a measured blade. “Frederick,” he said, as though tasting the name for accuracy. “So you’ve come. Good. Most boys arrive with courage on credit. We’ll see what you’ve earned.” He leaned on his gauntlet, studying Thunder’s stance, the set of my shoulders, the way I held the reins—everything a man did when he believed no one was watching. “Can you mount without looking like you’re wrestling a sack of grain?” “I can,” I answered, though my throat tightened. Sir Roland’s mouth quirked. “Then prove it. And when you’re done, you’ll learn how to stand where the danger can’t knock you loose.” He nodded toward the training yard, where shadows from the lanterns stretched like watching sentries. “First lesson: obedience. Second lesson: strength. Third lesson”—his eyes sharpened—“how not to waste either.” </nc-section> <nc-section data-title="Version 2: The Stable’s Lesson (Green)" data-color="green"> Sir Roland’s voice carried before I truly saw him. It came from the direction of the stables—steady, patient, and edged with authority. When I turned, he stood among the horses as if he belonged to the rhythm of their breathing. “Easy, old girl,” he murmured to a chestnut mare, then straightened and looked at me. His cloak hung heavy with morning-like damp despite the sunset heat, and his sword rested at his hip with the calm of something never far from readiness. “You’re Frederick,” he said. Not a question. “Yes, Sir Roland.” He gave a small, approving nod that felt warmer than the forge-fire glow. “Then you’ll start with what matters. Before steel, you learn care. Before courage, you learn timing.” He gestured toward a loose leather strap dangling from a saddle. “Fix that wrong knot. If you can’t keep a rider seated, you’ll never keep a promise.” I hurried to the tack, fingers fumbling for the proper loop, remembering the instructor’s words from the road: attention is a kind of power. The strap finally tightened—clean, secure. Sir Roland smiled faintly. “Better. Now—show me how you hold the reins when you’re nervous.” I swallowed. “Why would I ever—” “To find out,” he cut in gently. “Nervousness makes liars of our hands. We train until truth returns.” </nc-section> <nc-section data-title="Version 3: Steel and Silence (Blue)" data-color="blue"> Near the stables, where the horses stamped and the lanterns trembled in their hooks, Sir Roland approached without hurry. It wasn’t that he moved slowly—only that the world seemed to adjust to him. His boots made no unnecessary sound, and his eyes missed nothing: my grip on Thunder’s bridle, the dust on my boots, the tension in my wrists. “Frederick,” he said at last, greeting me as though we’d already fought the same battle in another life. I bowed, suddenly aware of how young I must look beside his worn armor. “Sir Roland. I’m honored to—” “Hm.” He cut the words off like a whetstone cuts dullness. “Honor is fine. But can you listen?” Before I could answer, he raised a hand. The stable sounds softened—at least, my attention did. I realized he wanted me to notice a rhythm: the steady breathing of horses, the scrape of a stall door, the distant creak of the castle timbers settling into night. “Good,” Sir Roland murmured, lowering his hand. “That’s the ear of a soldier. Now—tomorrow you’ll swing a sword until your arms forget your name. But tonight, you’ll learn the first rule: don’t rush the enemy’s shadow.” He stepped closer, and the smell of oil and steel wrapped around me. “You think danger comes only when it attacks. Sometimes it comes when you’re sure nothing’s happening.” He glanced toward the training yard, where the torchlight flickered against stone. “And tonight, Frederick, something is always happening.” </nc-section>
