<nc-section data-title="A Stern Welcome" data-color="red"> I reined Thunder to a halt just inside the castle walls, where the smell of hay and horseflesh rose from the stables. A tall knight in scarred plate armor stepped from the shadows, his hand resting on the pommel of his longsword. "You're the new squire," Sir Roland said, his voice like grinding stone. "Late, and on a horse too fine for a boy. Dismount. There's mucking out to be done before you sleep." </nc-section> <nc-section data-title="A Kindly Meeting" data-color="green"> As I swung down from the saddle, a warm laugh echoed across the cobblestones. Sir Roland emerged from the stable door, straw in his grizzled hair, his broad face creased with smile lines. "Frederick, at last! I've been waiting for a fresh pair of hands. How was the road? Come, let's see to your horse together before the evening meal." </nc-section> <nc-section data-title="An Ominous Greeting" data-color="blue"> Thunder's hooves had barely stilled when I noticed the knight leaning against the stable gate, his grey eyes unreadable in the fading light. Sir Roland said nothing at first, merely studying me as if I were a puzzle he had long expected. "So you've come," he murmured, almost to himself. "The last dragon's shadow still stretches far, boy. I hope you're ready for more than polishing armor." </nc-section>
