<nc-section data-title="Version 1: The Weight of a Name" data-color="red"> I had barely dismounted when I heard the clink of armor behind me. A tall knight with a weathered face and a crooked smile stood near the stable doors, one gauntleted hand resting on the pommel of his sword. "You must be Frederick," he said, his voice carrying the low rumble of distant thunder. "I am Sir Roland. I knew your father." The words struck me like a blow. I opened my mouth to speak, but he raised a hand to silence me. "Before you ask, lad — no, I won't tell you how he died. Not tonight. Tonight, you'll stable your horse, eat a hot meal, and sleep. Tomorrow, I'll teach you what it means to carry his name." He turned and walked toward the keep without looking back, leaving me alone with Thunder and a silence that felt heavier than any sword. </nc-section> <nc-section data-title="Version 2: A Knight of Few Words" data-color="green"> Near the stables, a broad-shouldered man in dented but well-kept armor leaned against a post, watching me approach with cool, appraising eyes. "Frederick?" he asked. I nodded, and he pushed himself upright. "Sir Roland. I'm to train you." I waited for more — a welcome, a word of advice, anything. He gave me none. He simply took Thunder's reins from my hand, ran a practiced eye over the stallion's legs and flanks, and grunted. "Good horse. Good instincts in the animal sometimes means good instincts in the rider. We'll see." He handed the reins back. "Stable him yourself. A squire tends his own mount. Meet me in the training yard at dawn. Don't be late." And with that, he was gone — as abrupt as a door closing. </nc-section> <nc-section data-title="Version 3: A Warm Welcome" data-color="blue"> The stables smelled of hay and horses, and the lantern light made everything feel softer than I had feared. A knight was there already, rubbing down a grey mare with slow, patient strokes. He looked up as I entered, and his face broke into an easy grin. "Frederick! By the Dragon, you've grown." He set down the brush and crossed to me, clasping my forearm in the warrior's grip. "Sir Roland. Your father wrote to me about you — endlessly, I might add. You would think you were the first squire in the history of the realm." I laughed before I could stop myself, and something loosened in my chest. "Come," he said, nodding toward Thunder. "Let's get this fine beast settled. Then you and I will have a talk, and I'll tell you everything you want to know — but only after you've eaten. You look half-starved, boy." For the first time since leaving home, I believed I might belong here. </nc-section>
