<nc-section data-title="The Stern Welcome" data-color="red"> As I dismounted, the heavy thud of plate armor announced a newcomer. Sir Roland stood by the stable entrance, his face a map of jagged scars and stern lines. He didn't offer a smile, only a critical glare that swept over my travel-worn tunic. "You're late, boy," he growled, the hilt of his sword catching the dying light. "Dragons don't wait for squires who dally. Take the stallion's tack off and muck the stalls before the sun finds the horizon." </nc-section> <nc-section data-title="A Lesson in Humility" data-color="green"> I had barely caught my breath when a shadow fell across me. Sir Roland emerged from the gloom of the stables, a curry comb in one hand and a steady, appraising look in his eyes. He motioned for me to approach, his movements fluid despite the weight of his mail. "Frederick," he said, his voice surprisingly soft. "The dragon wards are quiet today, but the horses sense the shift in the wind. A knight is only as good as the creature that carries him into the fire. Learn to care for this beast, and you might survive the week." </nc-section> <nc-section data-title="The Weight of the Blade" data-color="blue"> "Drop the reins," a voice commanded, cool and authoritative. I turned to find Sir Roland leaning against the stone archway, idly twisting a leather gauntlet in his fingers. He studied me with a detached curiosity that made my skin prickle. "So, you're the one they sent to handle the last of the brood? You look like you'd snap under the heat of a single breath." He stepped forward, his eyes glinting with a challenge. "I hope you brought more than just your curiosity, squire. We leave for the Dragon's Peak at dawn." </nc-section>
