<nc-section data-title="Version 1" data-color="red"> I guided Thunder through the castle gates and veered toward the long row of wooden stables just as the last rays of sunset bled across the sky. The smell of hay and oiled leather drifted on the evening breeze. Before I could swing down from the saddle, a tall figure stepped from the shadows between the stalls, armor catching the fading light like polished bronze. The local knight, Sir Roland, greeted me near the stables with a broad grin that split his weathered face. "So this is the eager squire everyone's been whispering about," he rumbled, offering a gauntleted hand. "Frederick, isn't it? Come, lad. We'll see to your horse first. A knight's mount is his second soul, after all." </nc-section> <nc-section data-title="Version 2" data-color="green"> The gates groaned shut behind me as I rode the final stretch to the stables, Thunder's hooves clopping softly against packed earth. Lanterns had already been lit along the eaves, painting the twilight in strokes of gold. A knight in a deep-green cloak stood beside a water trough, brushing down a dappled warhorse of his own. He looked up at my approach, eyes sharp beneath a scarred brow. The local knight, Sir Roland, greeted me near the stables with a short, appraising nod. "You're later than the ravens promised," he said, voice low and steady as tempered steel. "But you're here. That's the first test passed. Hand me those reins, Frederick. No squire of mine begins his training with a poorly tended mount." </nc-section> <nc-section data-title="Version 3" data-color="blue"> Dusk had fully claimed the courtyard by the time I reached the stables, the banners I had seen from the fields now hanging still and dark above me. I slid from Thunder's back, boots sinking into fresh straw, when a quiet cough drew my gaze. A knight stood in the wide doorway, his blue surcoat embroidered with a coiled silver dragon that seemed almost to shimmer in the lantern light. The local knight, Sir Roland, greeted me near the stables, studying me with an intensity that made the hairs on my neck rise. "Frederick," he said, speaking my name as though it carried weight beyond its letters. "The wind told me a squire was coming. It did not say the last dragon would be watching through his eyes. Come inside, lad. We have much to discuss before your training even begins." </nc-section>
