<nc-section data-title="Version 1: The Trial of Iron" data-color="red"> I pulled Thunder to a halt before the courtyard stables, the smell of hay and damp leather washing over me. Before my boots even touched the cobblestones, heavy footsteps echoed from the archway. Sir Roland stepped into the torchlight, an imposing silhouette clad in battered chainmail. His hand rested idly on the pommel of a broadsword that bore more notches than a veteran's tally stick. His steely gray eyes swept over me, lingering on the way I held my reins before settling on my face. "Late for muster, lad," Roland rumbled, his voice like grinding millstones. "Or perhaps just eager to let your beast outrun your sense. Hand the reins to the groom and draw your posture straight. In this castle, a squire's training begins the second his heels hit the stone." </nc-section> <nc-section data-title="Version 2: A Warm Welcome" data-color="green"> As Thunder trotted into the sheltered warmth of the outer stables, a cheerful shout cut through the evening quiet. "Steady there, young Frederick!" Emerging from one of the box stalls with a curry comb in hand was Sir Roland. He was a broad-shouldered man with crow’s feet etched deeply around kind, weathered eyes. Wiping straw from his leather doublet, he crossed the straw-strewn floor and extended a calloused hand in greeting, his grip firm and reassuring. "You ride with good hands; the stallion isn't even blown," Roland said with a nod of quiet approval, gently patting Thunder's damp neck. "I knew your father in our greener days, boy. If you have half his courage and twice his patience, you'll make a fine knight yet. Come, get your mount settled, and we'll see about a hot bowl of stew for you." </nc-section> <nc-section data-title="Version 3: Omens in the Sky" data-color="blue"> The stables were eerily quiet save for the nervous shifting of hooves and the low churring of swallows in the rafters. I swung down from the saddle, leading Thunder beneath the timber eaves, only to realize I was not alone. Sir Roland stood by the paddock gate, not looking at me, but staring up toward the darkened peaks of the Wyrmtooth Mountains. The torchlight caught the silver streaks in his dark beard and the grim furrow of his brow. Only when Thunder snorted did the knight finally turn, his expression burdened with heavy secrets. "So the summons reached you, Frederick," Roland spoke quietly, his tone devoid of fanfare. He looked me up and down, as if measuring whether my youth could withstand the storm gathering beyond our borders. "We have little time for the usual formalities of squire and knight. The northern outposts went dark two nights ago, and the old fires are stirring again. Tether your mount and come inside—we have much to prepare." </nc-section>
