<nc-section data-title="Version 1: The Stern Knight" data-color="red">
As I dismounted Thunder near the stables, a broad-shouldered knight stepped forward from the shadows. His armor was battle-worn, etched with the scars of a hundred conflicts. "You must be Frederick," he said, his voice like gravel grinding beneath a boot. Sir Roland crossed his arms and studied me with sharp, gray eyes. "I've trained dozens of squires. Most of them quit before the first frost." He gestured toward the stables with a gauntleted hand. "Tend to your horse. Then find me at the training yard. We begin at dawn — and I do not wait for stragglers."
</nc-section>

<nc-section data-title="Version 2: The Warm Welcome" data-color="green">
A hearty laugh rang out across the courtyard as I led Thunder toward the stables. Sir Roland strode toward me with a wide grin beneath his graying beard, his hand outstretched in welcome. "Ha! You made it before nightfall — a good sign already!" He clapped me firmly on the shoulder, nearly knocking me sideways. "I knew your father, boy. A finer swordsman never lived." His warm brown eyes softened for just a moment before he winked. "No pressure, of course. Come, let's get your horse settled and find you some supper. Training can wait until morning."

<nc-section data-title="Version 3: The Mysterious Greeting" data-color="blue">
The stables were quiet, save for the soft nickering of horses, when a figure detached itself from the darkness between the stalls. Sir Roland moved with an unsettling silence for a man in full armor. He said nothing at first, simply watching me with an unreadable expression as I tethered Thunder to the post. "I had a dream about you last night," he finally said, his voice barely above a whisper. "A boy on a black horse, riding toward a dragon made of shadow." He tilted his head slowly. "Tell me, Frederick — do you believe in fate?" The lantern light flickered between us, and somewhere deep in the castle, a bell began to toll.
