<nc-section data-title="Version 1" data-color="red"> I had just led Thunder into the shadow of the stables when a heavy gauntlet clapped down on my shoulder. "So, you're the new squire?" The voice was iron. Sir Roland stood before me, broad as a gate, his beard streaked grey and his surcoat smelling of sweat and horses. He looked me up and down, unimpressed. "Tethering your horse like that will get him lame by morning. Tie him loose, muck his stall, then find me in the yard. We'll see if Castle Alden has use for you." </nc-section> <nc-section data-title="Version 2" data-color="green"> Thunder was still snorting from the ride when a laugh boomed across the stable yard. "Welcome, welcome! You must be Frederick!" Sir Roland strode toward me, wiping straw from his hands, his ruddy face split in a grin beneath his close-cropped helm of grey hair. He took my pack before I could protest and clapped my back. "Fine stallion you've got there. Come, lad, stable him with mine — Old Bess won't mind company. You've ridden far, and the kitchens still have warm bread if we hurry." </nc-section> <nc-section data-title="Version 3" data-color="blue"> Dusk had settled over the stables by the time I slipped from Thunder's saddle. A tall figure was already waiting in the lantern-light. "Frederick," Sir Roland said quietly, as if he had known my name for years. His armor was old and unpolished, his eyes tired. He stroked Thunder's neck with a gentleness that surprised me. "They still send boys to train for wars that are already lost. Come. There is little time left, and if the old stories are true, you were called here for more than swordplay." </nc-section>
