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.

Here are three alternate prose sections continuing the story, one in each requested color: <nc-section data-title="Court of Stone and Steel" data-color="red"> Thunder’s iron-shod hooves rattled against the cobbles as I reined him in before the castle stables. Enter Sir Roland: tall, scarred, the sun glinting off mail as coarse as his beard. His voice was a rasp of chainmail and commands. “Boy,” he growled, seizing the bridle. “Name?” “Frederick, sir.” “Then dismount, Frederick, and begin earning the right to wear my armor someday. You’ll sleep where the hounds do until you prove otherwise.” </nc-section> <nc-section data-title="Whispers of Iron" data-color="green"> I swung from the saddle just as a tall knight emerged from the shadows cast by the stable roof. Sunlight pooled across the emerald band on his surcoat—Sir Roland, whose reputation had reached every village square. “Welcome to the keep, lad,” he said more quietly than his stature suggested, laying a gauntleted hand on my shoulder. “Care for your mount, then come find me in the east courtyard. The first lesson of knighthood begins at dusk.” A hint of amusement flickered behind his stern gaze. </nc-section> <nc-section data-title="Banner’s Echo" data-color="blue"> A moment later, stable boys scurried aside as Sir Roland approached, white surcoat and blue-flame sigil bright against the dusk. He measured me with a soldier’s unflinching stare. “New squire,” he said by way of greeting. “I’m Roland—hold Thunder for a moment longer while I fetch his tack. The castle gates are about to close; once they do, you’re inside until dawn. Make yourself useful inside the walls, or the night will find duties of its own.” </nc-section>
