My horse, a majestic stallion named Thunder, galloped across the open field. The wind whipped through my hair as I rode towards the castle gates. The sun was setting, casting a warm glow over the stone walls. I could see the banners of the kingdom fluttering in the breeze.

<nc-section data-title="The Greeting at the Stables - Version 1" data-color="red"> The stables stank of hay and horse-sweat, and Frederick was struggling to dismount when a voice cut through the din. "You must be the new squire. Frederick, is it?" Sir Roland stood with his arms crossed, his plate armor dented and mud-splattered from the day's patrol. His beard was more grey than brown, but his eyes were sharp enough to make Frederick straighten his back immediately. "You're late," Roland said, not unkindly, but without warmth. "And Thunder there looks half-starved. A squire who cannot care for his horse cannot care for his knight. Stable him, water him, brush him down. Then find me in the yard. Your training begins before supper." He gave Frederick's shoulder a brief, iron-hard squeeze as he passed — a greeting that felt more like a test. </nc-section> <nc-section data-title="The Greeting at the Stables - Version 2" data-color="green"> Frederick had barely led Thunder into the cool shade of the stables when a hearty laugh boomed behind him. "Well, look what the road dragged in! You must be Frederick!" Sir Roland was not at all what Frederick had imagined a knight to be. He was broad and ruddy-faced, his tabard stained, his sleeves rolled up to his elbows as he carried two buckets of water himself. He set the buckets down with a slosh and clasped Frederick's forearm in a grip that rattled his teeth. "Welcome, lad. I'm Roland. I hold this castle for the Duke, but around the stables, I'm just the fellow who makes sure these beauties get fed." He looked over Thunder with an expert's eye and nodded approvingly. "Fine horse. You've cared for him well on the road. Come, let's get him settled together, and you can tell me where you learned to ride like that. We heard you galloping a mile off." </nc-section> <nc-section data-title="The Greeting at the Stables - Version 3" data-color="blue"> Near the stables, where the light from the setting sun barely reached, a figure waited in stillness. Frederick reined Thunder to a stop, his heart hammering. The knight leaned against a post, his silvered armor reflecting the last light. A long cloak, the color of dusk, was draped over his shoulders. "Sir Frederick," the knight said, and his voice was quiet. "Or not yet Sir. Squire Frederick." He stepped forward. "I am Roland." He did not offer a handshake. Instead, he placed a hand on Thunder's quivering flank, and the great stallion instantly calmed. "The castle has been expecting you," Sir Roland continued, his gaze studying Frederick intently. "The stones... they remember the last time a boy arrived on a galloping horse at sunset. That was a long time ago, before the dragons left. Tell me, Frederick, on your ride here... did you see anything in the sky?" </nc-section>
