<nc-section data-title="Version 1: The Stables Greeting" data-color="red"> As the last rays of sunlight painted the courtyard red, Frederick dismounted Thunder and led the stallion toward the stables. The smell of hay and oiled leather filled his nostrils. Before he could step inside, a broad-shouldered man in gleaming armor stepped from the shadows, his tabard marked with the golden lion of the realm. “Frederick of Elderbrook?” the knight asked, voice like grinding stones softened by courtesy. “I am Sir Roland. I was told a new squire had been sent to us. Let us see whether your hands can grip a sword as surely as they grip reins.” He extended a gauntleted hand, the gesture half welcome, half challenge. </nc-section> <nc-section data-title="Version 2: The Stables Greeting" data-color="green"> Frederick had scarcely loosened Thunder’s girth when a figure in earth-toned surcoat appeared at the stable door. Sunlight caught on a green-enameled clasp at the knight’s collar as Sir Roland approached with the calm of someone who had seen both dawn charges and dusk retreats. “Easy, lad. The destriers grow restless when strangers fumble their tack.” He offered a faint smile, eyes the color of new leaves. “I am Sir Roland. The stable-master says you ride well; now let us discover whether you learn as quickly from men as you do from horses. Come—there is still light enough to show you the tilt-yard.” </nc-section> <nc-section data-title="Version 3: The Stables Greeting" data-color="blue"> The castle bells tolled the evening hour as Frederick stepped into the cool dimness of the stables. Thunder nickered softly, sensing tension before danger was voiced. From beside a row of polished saddles, Sir Roland emerged, armor catching cool twilight highlights like ripples on water. “Frederick,” the knight greeted, voice low yet carrying the clarity of a master who had commanded charges across rivers. “I am Sir Roland. I will be your guide through these first days. Unburden your horse, then present yourself to me at the armory. There is a lesson waiting, and the Keep’s stone grows cold quickly after sundown.” </nc-section>
