<nc-section data-title="Version 1: The Stables Encounter" data-color="red"> Frederick reined in Thunder just as the great wooden gate of the outer bailey swung shut behind him. Dust swirled around the horse’s legs while stable lads scurried forward. From the shadowed arch of the stone stables stepped a broad-shouldered knight whose crimson surcoat bore the spiraling crest of House Alric. Sir Roland’s weathered face split into a welcoming grin; he clapped a gauntleted hand on Frederick’s shoulder and said, “Easy, lad—the castle will not devour you before morning. Leave your stallion with young Tomas and walk with me. The Master of Arms expects new blood, and I mean to see you survive your first sunrise.” </nc-section> <nc-section data-title="Version 2: Greetings at Dusk" data-color="green"> The scent of hay and oiled leather drifted from the long stables as Frederick dismounted. A tall knight in green-enameled plate waited beneath a lantern blazing with verdant witch-light. Sir Roland bowed slightly, the plume on his helm brushing the low beam. “Frederick of Oakvale, the ride has put fire in your eyes. Good. The realm has little patience for idle squires. Stable your mount, then follow; I shall show you the armory and the meal hall both—tradition demands a new squire eats before he bleeds.” </nc-section> <nc-section data-title="Version 3: Sir Roland's Welcome" data-color="blue"> Thunder’s hooves struck the cobbles beside the blue-bannered stables when a calm voice cut through the evening air. Sir Roland, clad in indigo-tinted mail that caught the last light like river water, stood with one hand resting on the hilt of his longsword. “Welcome to Castle Drakespire, young Frederick. I am Roland of the Silverwing Order. Your journey ends here, yet a greater road begins. Secure your horse, then walk beside me; there are secrets these walls keep, and none may learn them thirsty or alone.” </nc-section>
