<nc-section data-title="Version 1: The Stern Welcome" data-color="red"> The clatter of hooves faded as Frederick reined Thunder to a halt in the castle courtyard. A burly knight in battered silver armor strode from the stable’s shadow, his gauntleted hand resting on his sword’s pommel. “So, you’re the new squire,” Sir Roland growled, his voice like grinding stone. He frowned at Thunder’s proud posture. “Keep that beast out of my stables until he’s been properly brushed. And mind your tongue—I’ve no patience for dreamers.” He turned and barked orders to a stable boy without waiting for a reply. </nc-section> <nc-section data-title="Version 2: The Refined Greeting" data-color="green"> The scent of hay and leather filled Frederick’s nostrils as he slid from Thunder’s saddle. A tall, clean-shaven knight in polished plate armor approached with an easy stride, his hand raised in casual salute. “Ah, young Frederick, I presume? I am Sir Roland.” His smile was warm but measured. “The stable hands will see to your horse—fine animal, by the way. Come, the steward has prepared a light meal in the hall. We can speak of your training on the way.” He offered a friendly clap on Frederick’s shoulder and gestured toward the inner gate. </nc-section> <nc-section data-title="Version 3: The Mysterious Aura" data-color="blue"> A figure emerged from the stable’s gloom as Frederick dismounted—a knight whose dark cloak stirred as if touched by an unseen breeze. His eyes, pale as winter ice, studied the boy with quiet intensity. “You ride well,” Sir Roland said, his voice low and resonant. “But the road ahead is not one of wind and hoofbeats.” He turned, the stable lanterns casting long shadows. “Leave your horse; I will show you to the tower where your true journey begins.” Without another word, he walked away, expecting Frederick to follow into the deepening twilight. </nc-section>
