<nc-section data-title="Version 1" data-color="red"> I led Thunder toward the stables, where a broad-shouldered knight stood watching the last light fade from the castle walls. “Frederick, I presume?” he said. “I’m Sir Roland.” He took Thunder’s reins while I climbed down. “You’ve arrived just in time for supper. Tomorrow, we’ll see whether you can hold a sword as well as you ride.” </nc-section> <nc-section data-title="Version 2" data-color="green"> As I brought Thunder to a halt beside the stables, a knight emerged from the shadows, wiping his hands on a cloth. His armor was scarred, and a faded dragon was stitched upon his cloak. “Welcome to the castle, Frederick,” he said. “Sir Roland, at your service.” His gaze lingered on Thunder. “Settle your horse, then come find me. There’s something you should know about the hills beyond these walls.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> Thunder shied at the smell of the stables, nearly pulling the reins from my hands. A knight caught them before I could stumble. “Easy there,” he murmured, stroking the stallion’s neck. “And welcome, Frederick. I’m Sir Roland.” I thanked him, embarrassed, but he only smiled. “Don’t worry. My first day here, I fell into the horse trough. Let’s get your mount fed before you improve on that.” </nc-section>
