<nc-section data-title="Version 1" data-color="red"> As I dismounted Thunder, a broad-shouldered knight with steel-gray eyes and a neatly trimmed beard approached from the stables. “Frederick of Edensbridge, I am Sir Roland,” he announced, his voice carrying the easy command of a veteran leader. He gripped my forearm in a firm clasp and nodded toward the stables’ open doors. “Leave your gear with the grooms; the king commands your training begin at dawn.” </nc-section> <nc-section data-title="Version 2" data-color="green"> No sooner had I slid from the saddle than a tall, ruddy-faced knight emerged from the shadows of the stable archway, sunlight glinting off the polished silver of his armor. “Squire Frederick,” he said with a warm, rumbling laugh, “Sir Roland at your service. Let’s see if that fancy riding of yours holds up in full plate tomorrow.” He clapped me heartily on the shoulder and motioned for the stable hands to take care of Thunder. </nc-section> <nc-section data-title="Version 3" data-color="blue"> A sudden clank of spurs announced the arrival of a lean, weather-worn knight from between rows of hay-filled stalls. Sir Roland studied me with calculating blue eyes, his gauntleted hand resting on the pommel of his longsword. “I’ve been told you possess promise, Frederick,” he stated quietly. “At dawn, we shall see whether promise alone is enough.” </nc-section>
