<nc-section data-title="Version 1: The Stern Welcome" data-color="red"> Sir Roland stood near the stable entrance with his arms crossed, his armor catching the last rays of sunset like burnished copper. He watched Frederick dismount with a critical eye, his weathered face unreadable beneath his steel helm. "You're late, boy," he said, his voice a gravelly rumble that carried across the cobblestones. "The stables don't clean themselves, and neither do squires who arrive after the sun begins its descent. Drop your pack and get to work—I don't have all evening to stand here admiring the view while you catch your breath." </nc-section> <nc-section data-title="Version 2: The Warm Mentor" data-color="green"> Sir Roland leaned against the stable door, whittling a piece of oak with practiced ease. When he spotted Frederick guiding Thunder toward the hitching post, he set down his knife and broke into a genuine smile. "Well, look who finally made it! You must be Frederick. I'm Sir Roland." He extended a calloused hand, firm but kind. "Come, let me show you where you'll be sleeping. We've got a long day ahead of us tomorrow, and you'll want to rest those legs after such a ride. Don't worry—we'll make a knight of you yet, but first, let's get you settled in." </nc-section> <nc-section data-title="Version 3: The Eccentric Knight" data-color="blue"> Sir Roland was kneeling in the straw near the stable entrance, vigorously brushing a shaggy, sheep-sized hound that looked more like a bear than a dog. He glanced up at Frederick with hay tangled in his auburn beard and wide, cheerful eyes. "Ah! The new squire, are you? I'm Sir Roland, though between you and me, I think Brutus here is the one with the real authority around these parts." He scratched the dog behind the ears, causing it to thump its tail against the wooden wall. "Now, if you're going to stand there gaping like a landed trout, you might as well help me carry these feed sacks inside. Brutus gets terribly hungry after all that... uh... important guarding he does." </nc-section>
