<nc-section data-title="Version 1: The Stern Welcome" data-color="red"> Sir Roland stood tall beside the stable doors, his scarred hand resting on the pommel of his sword. As Frederick dismounted, the knight’s gravelly voice cut through the twilight. “You’re the new lad? Keep your wits sharp and your mouth shut. The castle doesn’t forgive fools.” His gaze was flint-hard, and the stable boy scurried away, leaving only the stamp of hooves and the weight of expectation. </nc-section> <nc-section data-title="Version 2: The Warm Greeting" data-color="green"> A soft laugh rolled from the shadows as Frederick tied Thunder’s reins. Sir Roland emerged, his weathered face creased with a kindly smile. “Easy there, young one. I remember my first night—nervous as a hare in a fox’s den.” He clapped Frederick on the shoulder, leading him toward the hay-strewn aisle. “Come, let’s get your horse fed. There’s stew in the hall, and a tale or two if you’ve ears for them.” </nc-section> <nc-section data-title="Version 3: The Silent Observer" data-color="blue"> Frederick felt a presence before he saw him. Sir Roland leaned against the stable’s oak frame, arms crossed, saying nothing. The only sounds were Thunder’s soft snorts and the creak of leather. When their eyes met, the knight offered a slow nod—no words, but a gesture that spoke of patience and deep understanding. Then he turned and walked toward the castle, expecting Frederick to follow. The silence was an invitation, not a command. </nc-section>
