<nc-section data-title="Version 1: The Knight at the Stables" data-color="red"> Near the stables, a broad-shouldered knight stepped out to meet me. His polished armor caught the last light of the setting sun, and a red plume nodded from his helmet. “Frederick, I presume?” he said, offering a gloved hand. “Sir Roland. Welcome to the castle.” I swung down from Thunder’s saddle and returned his greeting. The knight’s gaze lingered on my travel-worn clothes, but his smile was warm. “Come along,” he said. “Your training begins at dawn. For tonight, let’s find your horse some hay—and you a bed.” </nc-section> <nc-section data-title="Version 2: A Warm Welcome" data-color="green"> A man in a green cloak waited beside the stable doors, one hand resting on the pommel of his sword. As I led Thunder closer, he gave a cheerful nod. “You must be Frederick,” he said. “I’m Sir Roland, the knight assigned to show you around.” I glanced at the castle rising beyond him. “I’m glad to meet you, sir.” “And I’m glad you’ve arrived before the gates are shut,” Roland replied with a grin. He reached for Thunder’s reins. “Let’s get your stallion settled. Then I’ll show you where a new squire is expected to be at sunrise.” </nc-section> <nc-section data-title="Version 3: The Watchful Knight" data-color="blue"> A figure emerged from the shadow of the stables as I approached. His blue sash marked him as a knight of the king’s household, and his steady eyes took in my horse, my baggage, and me. “Frederick?” he asked. “Yes, sir.” “Sir Roland.” He gave a brief nod, then softened his stern expression. “You’ve had a long ride. The stable hands will care for your horse, and I’ll see you safely to the squire’s quarters.” As he led the way, Thunder followed at my shoulder. “Rest while you can,” Sir Roland added. “Tomorrow, we begin to discover what you’re made of.” </nc-section>
