<nc-section data-title="The Stable Greeting - Version 1" data-color="red"> Frederick had barely dismounted from Thunder near the stables when a shadow fell across him. "You the new squire?" a gruff voice barked. Sir Roland stood with arms crossed, his plate armor dented and mud-flecked from the field, his grey beard cropped short. He looked Frederick up and down, unimpressed. "Stable your beast. Rub him down yourself — no servant does your work here. Then report to the yard at dawn. If you're late, you'll muck stalls for a week." Without another word, he turned on his heel, leaving the smell of leather and steel in his wake. </nc-section> <nc-section data-title="The Stable Greeting - Version 2" data-color="green"> The stable doors were already swinging open as Frederick led Thunder in from the sunset field. A broad-shouldered knight with a kind, weathered face stepped forward to take the horse's bridle. "Easy, lad, easy," Sir Roland said with a laugh, first to the stallion, then to the boy. "Welcome to Stonehollow, Frederick. Thunder, is it? Fine animal." He clasped Frederick's shoulder warmly. "You must be weary from the road. The stablehands will see to your horse — walk with me, and I'll show you where the squires sup. Training begins tomorrow, but tonight, you rest." </nc-section> <nc-section data-title="The Stable Greeting - Version 3" data-color="blue"> Twilight deepened around the stables, and the banners had gone still. As Frederick guided Thunder toward the lantern-light, a tall figure was already waiting in the doorway, motionless. "Frederick," Sir Roland said quietly, as if he had known his name for years. His eyes, pale and sharp, flicked to the stallion, then to the long shadow of the castle wall. "The dragons are gone and the old roads wake. You arrived at an hour foretold." He took a step closer and lowered his voice. "Stable your horse quickly. What I must tell you of your training cannot be spoken where others hear." </nc-section>
