<nc-section data-title="Version 1" data-color="red"> Near the stables, a broad-shouldered knight waited beneath the archway, his silvered armor catching the last light of sunset. He gave Frederick a courteous nod. “Frederick, I presume? I’m Sir Roland. Welcome to the castle.” Before Frederick could answer, a horse stamped in its stall, rattling the tack on the wall. Sir Roland glanced toward the sound with a knowing smile. “Best get used to that,” he said. “The stables are full of creatures with stronger opinions than most knights.” </nc-section> <nc-section data-title="Version 2" data-color="green"> The clatter of hooves slowed beside the stables. A knight in a green-trimmed cloak stepped forward, one hand resting on the pommel of his sword. “You must be the new squire,” he said. “Frederick, isn’t it? Sir Roland.” He offered his hand, weathered and warm. Behind him, the stable doors stood open, spilling the scents of hay and leather into the twilight. “Come along,” Sir Roland said. “Your training begins early—and the horses will want to know who’s arrived before the rest of the castle does.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> A lantern bobbed beside the stables, revealing a knight with a scar across his chin and a smile that softened it. He raised a hand to halt Frederick. “Easy there, young rider. I’m Sir Roland, the castle’s local knight. You’ve made good time.” Thunder snorted as the stablehands hurried out. Sir Roland studied the stallion with admiration, then turned his gaze to Frederick. “I see you’ve brought a companion. Let’s find him a stall—and then I’ll show you where a squire is expected to be at dawn.” </nc-section>
