<nc-section data-title="Version 1" data-color="red"> Passing through the iron portcullis, I guided Thunder toward the sprawling wooden stables. Before my boots even touched the cobblestones, a towering shadow fell over me. A broad-shouldered knight in dented silver plate stood with his arms crossed, a jagged scar running down his weathered cheek. "You're late, boy," the man rumbled, his voice like grinding stones. He stepped forward, his sharp gray eyes appraising my mud-splattered cloak before softening slightly as he looked at my mount. "Though I suppose a beast as fine as that warrants a slow, careful ride. I am Sir Roland. Get your gear stowed and your horse brushed down. Your training begins before the sun clears the eastern peaks." </nc-section> <nc-section data-title="Version 2" data-color="green"> The scent of fresh hay and woodsmoke welcomed me as I trotted into the outer bailey. Near the bustling stables, a man with a booming laugh was clapping a stablehand on the shoulder. When he spotted me, his face broke into a wide, welcoming grin. He wore a surcoat bearing the royal crest, though his armor was currently traded for a simple leather jerkin stained with oil. "Aha! Fresh blood at last!" he bellowed, striding over to catch Thunder's bridle with a practiced hand. "You must be Frederick. I'm Sir Roland, master-at-arms for this lively heap of stone." He patted Thunder's neck affectionately. "Climb on down, lad. You look like you've ridden half the realm today. Let's get your mount fed and find you some hot stew." </nc-section> <nc-section data-title="Version 3" data-color="blue"> Inside the courtyard, the air grew strangely quiet, save for the rhythmic *shhh-zing* of a whetstone. Near the entrance to the stables sat an older knight upon an upturned barrel, methodically sharpening a bastard sword. He didn't look up as I dismounted, allowing the silence to stretch until Thunder let out an impatient snort. Finally, the knight tested the blade's edge with his thumb and sheathed it with a decisive *clack*. He rose with a fluid grace that belied the grey in his beard. "A heavy hand on the reins, and your posture is stiff," he observed quietly, walking a slow circle around me. "I am Sir Roland. If you wish to survive what is coming, Frederick, you will need to unlearn everything you think you know about riding—and fighting. Come. The stable master will show you where you sleep." </nc-section>
