<nc-section data-title="Version 1" data-color="red"> Near the stables, a broad-shouldered knight stepped into the fading light. His silver breastplate bore the castle’s golden stag, and a scar crossed one cheek. “Frederick, I presume,” he said, taking Thunder’s reins with an easy confidence. “I’m Sir Roland. The castle has been expecting you.” Frederick swung down from the saddle, legs trembling after the long ride. “I’m honored, sir.” Roland glanced at the darkening sky. “Save your honors for tomorrow. Tonight, we’ll see you fed, settled, and safely indoors. These walls have a way of seeming less welcoming after sunset.” </nc-section> <nc-section data-title="Version 2" data-color="green"> The stable doors stood open, spilling the warm smell of hay into the evening air. A knight waited beside them, one hand resting on the pommel of his sword. “You must be Frederick,” he said. “Sir Roland, at your service.” Frederick dismounted and offered a nervous bow. “I’m to begin my training here, sir.” “So I’ve heard.” Roland studied him for a moment, then gave a small, approving nod. “The first lesson is that a tired horse needs water before a tired squire needs supper. Bring Thunder inside. We’ll talk while you see to him.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> A figure emerged from between the stables as Frederick rode through the gate. The man wore a weather-darkened cloak over his armor, and the stablehands greeted him with respectful nods. “Frederick?” he called. “Yes, sir.” “I am Sir Roland, the local knight.” He took Thunder’s bridle and gave the stallion a practiced look. “You’ve ridden hard. Let’s get him settled before we introduce you to the rest of the castle.” Roland led them toward the stable, but paused at the threshold. For just an instant, his gaze lifted to the western tower, where a faint blue light flickered behind the windows. “Stay close tonight,” he murmured. “And if you hear anything strange, wake me.” </nc-section>
