<nc-section data-title="Red Version: A Stern Welcome" data-color="red"> As I reined Thunder to a halt before the stable doors, a tall knight clad in weathered plate armor stepped out from the shadows of the hayloft. His gauntleted hand rested on the pommel of his sword, and his eyes narrowed as they assessed me. “You’re late, squire,” Sir Roland said, his voice a low rumble that matched the distant thunder. “The sun has nearly set, and I was beginning to think you’d lost your nerve.” He gestured toward a vacant stall. “Get that horse settled, then report to the armory. We’ll see if your courage holds as steady as your mount’s hooves.” </nc-section> <nc-section data-title="Green Version: A Warm Greeting" data-color="green"> I guided Thunder through the open stable gate, the scent of fresh hay and horseflesh welcoming me. A broad-shouldered knight with a kind face and twinkling eyes appeared, wiping his hands on a cloth. “Ah, you must be Frederick!” Sir Roland exclaimed, his voice as warm as the evening sunlight. “I’ve been watching for you from the tower. What a fine steed you have—Thunder, isn’t it? Come, let’s get him watered and fed, then I’ll show you to your quarters. You’ll find the castle folk eager to make you feel at home.” </nc-section> <nc-section data-title="Blue Version: A Cryptic Encounter" data-color="blue"> The stable courtyard was quiet save for the soft nicker of horses and the distant clang of the blacksmith’s hammer. I had barely dismounted when a figure emerged silently from the gap between two stalls, his armor oiled so smoothly it made no sound. Sir Roland studied me with an unreadable expression, then glanced at the sky. “The last squire stood here at sunset, just like you,” he said, his tone oddly distant. “He rode out the next morning and never returned. I trust you’ll fare better.” He took Thunder’s reins before I could reply, his touch surprisingly gentle. “Follow me. There are things you must know before dawn.” </nc-section>
