<nc-section data-title="Version 1" data-color="red"> Thunder slowed to a trot as we passed through the castle gates. Near the stables, a knight in a crimson cloak waited beside the open doors. He looked me over as I dismounted. “Frederick?” he asked. “I’m Sir Roland. You’re late.” My stomach tightened. “The road was muddy, sir.” “Then tomorrow we’ll see how well you rise after a long ride.” His stern expression softened just enough to give me hope. “See to your horse, then come find me. Your training begins at dawn.” </nc-section> <nc-section data-title="Version 2" data-color="green"> Thunder’s hooves clicked across the courtyard stones. A man emerged from the stables with a bundle of fresh hay beneath one arm, his knight’s sword hanging at his hip. “You must be Frederick,” he said. “I’m Sir Roland.” I swung down and bowed, nearly catching my spur on the saddle. Sir Roland steadied me before I could fall. “First lesson,” he said, smiling as he took Thunder’s reins. “Keep your feet beneath you. Come along—I’ll show you where he’ll sleep.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> As I led Thunder toward the stables, a knight stepped out of the dusk. Silver threaded his beard, and an old scar crossed one eyebrow. “Frederick,” he said, as though he had been expecting me all evening. “I am Sir Roland.” I bowed. Behind him, the stable horses shifted uneasily in their stalls. A low sound rolled across the hills, too deep to be thunder. Sir Roland heard it too. He glanced toward the darkening sky, then back at me. “Get your horse inside, lad. We have much to discuss.” </nc-section>
