<nc-section data-title="Version 1: The Stern Greeting" data-color="red"> By the time Thunder’s hooves sounded on the packed earth of the stables, Frederick could smell straw and iron—old work and older battles. A cluster of men were settling harnesses when a heavy boot scuffed near him. Sir Roland emerged from the shadow of the tack room like a weathered tower given legs. His armor was polished to a dull, soldierly sheen, and the surly curl of his mustache suggested he’d rather be argued with than comforted. “You’re the squire they’ve sent,” Sir Roland said, not quite a question. His gaze traveled over Frederick’s clothes, his saddle, even the way he held his reins, as if tallying every flaw. “Mind your posture. A man who slouches invites trouble. And trouble is always looking for new blood.” Frederick swallowed, trying to steady his voice. “Sir—yes, my lord. Frederick. I’m ready to—” Sir Roland lifted a gauntleted hand, halting him mid-pledge. “Ready is cheap. Prove it.” He nodded toward the yard where a half-cracked training dummy leaned against a post. “First task: keep your horse calm and your eyes open. The rest comes after.” </nc-section> <nc-section data-title="Version 2: Courtesy with Teeth" data-color="green"> Frederick guided Thunder into the stable yard, where lantern-light bounced off polished metal and the horses’ breath steamed in the coolening air. He’d expected silence or stern stares, but before he could tie off the reins, a familiar clatter approached—measured, deliberate. Sir Roland appeared beside the feed trough as though he’d been there all along. He wore his crest like a promise: not friendly, not cruel—just certain. When he spoke, his voice carried the calm authority of a man who’d said the same words to a hundred frightened newcomers. “So you’ve finally arrived, squire.” He offered a brief nod, courteous enough to make Frederick straighten his spine. “I am Sir Roland, and I’ll be watching you. Not because I’m eager to find faults—though we all have them—but because the work demands it.” Frederick managed a respectful bow. “I’ll do my best, my lord.” “Good,” Sir Roland replied. Then, with a small turn of his head toward Thunder, his expression softened by a fraction. “Your horse—walk him once before you harness. Loose steps, quiet hands. If you frighten him, you’ll frighten yourself, and both will learn the lesson the hard way.” He gestured toward the stable gates. “We begin with discipline. And discipline begins now.” </nc-section> <nc-section data-title="Version 3: A Flash of Humor" data-color="blue"> The stables were warmer than the yard, filled with the sweet tang of hay and the gossiping sounds of shifting tack. Frederick was tightening Thunder’s cinch when he heard laughter—low at first, then unmistakable. “Easy there,” said a voice thick with amusement. “If you pull any harder, your horse will file a complaint with the moon.” Frederick turned. Leaning casually against a doorframe stood Sir Roland, armor unbuckled at the shoulder as if he’d stepped out of battle long enough to breathe. His eyes, dark and sharp, carried a spark that didn’t match the stern stories. “You’re the new squire,” Sir Roland continued, as though confirming an obvious guess. He took in Frederick’s earnest face and clumsy hands, then chuckled again. “Relax. You can tighten a girth without wrestling it.” Frederick flushed. “I’m sorry, my lord. I meant to—” “To do it right?” Sir Roland finished, already stepping closer. He guided Frederick’s hands to the proper strap, demonstrating a surety that made it look effortless. “See? Careful, steady. Like forging steel—no rushing, no panic.” Then the humor slipped away, leaving only resolve. “Listen well, Frederick. The castle will test you in a dozen ways. But if you remember this: your strength is useless without control, you’ll last long enough to learn the rest.” </nc-section>
