<nc-section data-title="Version 1" data-color="red"> Near the stables, a broad-shouldered knight waited beneath the fluttering banners. His polished armor caught the last red rays of sunset. “Frederick, I presume?” he called, stepping forward. “I’m Sir Roland, and I’ll see you settled in.” Frederick dismounted, trying not to stumble as Thunder tossed his mane. Sir Roland gave the stallion an approving glance, then offered Frederick a firm handshake. “Welcome to the castle,” he said. “Your training begins at dawn. For tonight, let’s find your horse a stall—and you a bed.” </nc-section> <nc-section data-title="Version 2" data-color="green"> The stable doors stood open, breathing out the warm scent of hay and horses. A knight in a green cloak waited beside them, one hand resting on the pommel of his sword. “You must be Frederick,” he said with a smile. “Sir Roland, at your service.” Frederick slid from Thunder’s saddle and bowed awkwardly. Sir Roland steadied him with a hand on his shoulder. “Easy there. The first lesson is learning how to get off a horse without meeting the ground.” He led them inside. “Come along. I’ll show you where you’ll be staying—and introduce you to the other squires.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> A figure emerged from the shadows between the stables and the castle wall. Blue dusk gleamed on the knight’s mail, and a silver dragon clasp fastened his cloak. “Frederick?” he asked. “I’m Sir Roland, the castle’s knight-captain.” Frederick nodded, suddenly aware of how small he felt beside him. Roland’s gaze moved from the young squire to Thunder, whose hooves clattered softly on the cobbles. “Good. You’ve arrived before nightfall.” Sir Roland turned toward the stable doors. “Bring your horse inside. There’s much to learn here, and not all of it can be taught with a sword.” </nc-section>
