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="Alternate 1: A Red Greeting" data-color="red"> The local knight, Sir Roland, greets Frederick near the stables. His crimson surcoat gleams in the last light of dusk, the emblem of a roaring lion stitched over his breastplate. “Welcome to Castle Avelorn, squire,” he says, offering a firm hand. Frederick bows, heart pounding, as Roland’s warm eyes study him. “Your first lesson begins tomorrow at dawn,” the knight continues. “Rest well, and know that honor and courage will guide you better than any blade.” Roland places a reassuring hand on Frederick’s shoulder before riding off, leaving the young squire with both confidence and anticipation for the days ahead. </nc-section> <nc-section data-title="Alternate 2: A Green Greeting" data-color="green"> The local knight, Sir Roland, greets Frederick near the stables. He jangles a set of horseshoes at Frederick’s feet and grins broadly. “If you’re half as eager as your horse, lad, we’ll make a knight of you yet!” Roland teases, looping an arm through Frederick’s. The squire chuckles nervously as Roland points to a row of saddles. “Meet me by the riding ring in an hour. Your first task: learn to mount without falling flat on your face.” Frederick straightens, determination flickering behind his wide eyes. As Roland strides away whistling a lively tune, the young squire drags his feet toward the farrier, ready to prove himself under the knight’s watchful—and mischievous—gaze. </nc-section> <nc-section data-title="Alternate 3: A Blue Greeting" data-color="blue"> The local knight, Sir Roland, greets Frederick near the stables. His voice is calm, edged with authority. “Frederick,” he says, “this castle holds secrets older than any of us. Trust in discipline.” The squire nods, inhaling the crisp night air laced with hay and horses. Roland leads him past a row of steeds, their eyes reflecting torchlight. “Tomorrow at dawn, we ride through the Whispering Woods. I expect you to keep pace and your wits about you.” A shadow of warning passes over the knight’s face. Frederick feels a chill—not from the cold—but from the weight of expectation. As Roland turns toward the castle walls, Frederick steels himself for the hidden challenges that lie ahead. </nc-section>
