<nc-section data-title="Version 1: The Veteran's Welcome" data-color="red"> As I guided Thunder through the formidable archway of the castle, the smell of damp straw and leather drew me toward the stables. Dismounting, my boots sank slightly into the wet earth. Out of the shadows of the stable block stepped a broad-shouldered man wearing a worn leather jerkin over chainmail. His hair was cropped short and peppered with gray, and a deep scar cut across his left cheek. "You must be the new squire," the man said, his voice deep and gravelly like grinding stones. He walked over, running a critical but appreciative hand over Thunder’s neck. "An impressive beast. I am Sir Roland. Around here, we care for our mounts before we care for ourselves. Strip his saddle, rub him down, and then we shall see if you have the stomach for what comes next." </nc-section> <nc-section data-title="Version 2: A Warm Reception" data-color="green"> I pulled Thunder to a gentle halt outside the bustling stables, where stablehands were hurrying about under the glow of early lanterns. Before I could even swing my leg over the saddle, a boisterous laugh echoed from the stable doors. A tall knight with a bright smile and a neatly trimmed beard strode out, his blue cloak billowing slightly behind him. "Ah, the traveler arrives!" the knight cried, throwing his arms wide in a welcoming gesture. "Welcome to Wyvernshear, lad! I am Sir Roland." He reached up to offer me a hand down, his grip firm and reassuring. "You’ve made good time. Thunder, is it? A fine stallion. Come, let’s get him fed and watered, and I'll show you to the mess hall. You look like you could eat an entire boar." </nc-section> <nc-section data-title="Version 3: The Trial of the Gates" data-color="blue"> The heavy iron gates groaned as they closed behind me, shutting out the wild lands. I dismounted near the stables, my joints stiff from the long journey. Standing by the stable doors, arms crossed over a polished breastplate that reflected the dying sunlight, was Sir Roland. He was a man of cold, calculating eyes, assessing me with a single, sweeping gaze that made me feel painfully young and underprepared. "You ride well enough, Frederick, but speed is nothing without discipline," Sir Roland said, his tone sharp and quiet. He didn't offer a hand, nor did he smile. "A squire's life is one of absolute obedience and tireless labor. Your training begins the moment you step foot on this stone. Stable your horse, present yourself to the armory, and do not keep me waiting. The peace of this realm does not wait for boys to find their footing." </nc-section>
