<nc-section data-title="Version 1" data-color="red"> Near the stables, a broad-shouldered knight in a weathered red cloak stepped forward to meet me. His armor was scratched, his gray mustache neatly trimmed, and his eyes bright with amusement. “You must be Frederick,” he said, offering a gauntleted hand. “I’m Sir Roland. Welcome to the castle—though I warn you, the horses are friendlier than the cooks.” I laughed, glad to find a face waiting for me. Behind him, the stable doors stood open, and from within came a low, rumbling sound that was far too deep to belong to any ordinary horse. </nc-section> <nc-section data-title="Version 2" data-color="green"> I had barely dismounted near the stables when a knight strode out to greet me. He wore a green sash over his polished armor, and a silver dragon was etched upon his shield. “Frederick, I presume?” he asked. “Sir Roland, at your service. You’ve arrived just in time.” “For what?” I asked, glancing toward the castle. Roland’s smile faded. From somewhere beyond the stable walls came a sharp clang, followed by the frightened whinny of a horse. The knight turned toward the sound and reached for his sword. </nc-section> <nc-section data-title="Version 3" data-color="blue"> A stablehand hurried to take my horse’s reins, and a knight approached through the dusk. Blue light from the evening sky gleamed along the edge of his armor. “Frederick?” he said. “I’m Sir Roland. I’ve been expecting you.” His greeting was warm, but his gaze kept wandering toward the dark stable doors. As I followed his eyes, I noticed a thin trail of smoke slipping beneath them. “Is something wrong?” I asked. Roland drew a quiet breath. “Something has been waking in the stables,” he said. “And tonight, I fear it knows you’re here.” </nc-section>
