My horse, a majestic stallion named Thunder, galloped across the open field. The wind whipped through my hair as I rode towards the castle gates. The sun was setting, casting a warm glow over the stone walls. I could see the banners of the kingdom fluttering in the breeze.

<nc-section data-title="Version 1: The Greeting by the Stables" data-color="red"> Frederick steadies Thunder as the last light bleeds from the sky. Near the stables, a shadow falls across the cobbles and a figure steps into the lantern glow. Sir Roland, the local knight, strides forward with practiced ease, armor glinting and cloak snapping at his heels. He stops before Frederick, tilting his helm in a respectful nod. "Frederick," he says in a low, steady voice, "welcome to the castle. I am Sir Roland, your guide and guardian in these halls." The handshake is firm, and in that grip Frederick feels the weight of what lies ahead as the first lesson begins. </nc-section> <nc-section data-title="Version 2: The Knight's Welcome" data-color="green"> Sir Roland greets Frederick near the stables with blunt courtesy and a glint of approval. He steps from the dim line of stalls, armor catching the orange glow, and rests a gloved hand on Frederick’s shoulder for a moment. "You must be the new squire," he says. "I am Sir Roland, keeper of this wing. Here we measure more than strength—what you hold in your heart will steer your sword." He motions toward the training yard, and with a curt nod invites Frederick to follow, the weight of years in his gaze. </nc-section> <nc-section data-title="Version 3: A Knight's Banter" data-color="blue"> Near the stables, Sir Roland appears from the shade, helmet tucked under his arm and a half-smile tugging at the corners of his mouth. He steps up to Frederick as Thunder snorts and shifts his weight. "So, you’re Frederick," he says, voice even and teasing just enough to loosen the tension. "If you can handle a horse and a rumor, you can handle a knight." He claps Frederick on the shoulder—not too hard—and gestures toward the yard. "Let’s see what you’re made of, squire. Your first test is not in your legs alone but in your judgment and your will." </nc-section>
