<nc-section data-title="Version 1" data-color="red"> Near the stables, Frederick swung down from Thunder’s saddle, his legs stiff from the ride. A tall knight in a weatherworn cloak stepped out to meet him, one hand resting on the pommel of his sword. “You must be Frederick,” he said. “Sir Roland. Welcome to the castle.” Frederick bowed, trying not to show how nervous he felt. Sir Roland’s gaze flicked to the young squire’s travel-stained clothes, then softened. “Come along,” the knight said. “The horses are glad to see you—and the captain has been asking when you’d arrive.” </nc-section> <nc-section data-title="Version 2" data-color="green"> Thunder snorted as Frederick led him toward the stables. A knight waiting beneath the lantern by the stable doors raised a hand in greeting. His silver hair shone in the last light of sunset. “Frederick?” he asked. “I’m Sir Roland, the castle’s own knight. I’d know that determined look anywhere.” Frederick glanced at the mud on his boots. “I hope it looks more determined than exhausted, sir.” Sir Roland laughed and took Thunder’s reins. “A little of both, perhaps. Come inside. We’ll see your horse settled, and then I’ll show you where a squire ought to be.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> At the stable yard, Frederick found a knight waiting beside the open doors. A lantern swung from a beam above him, throwing gold light across his polished breastplate. “Frederick,” the knight greeted him. “Sir Roland. I was beginning to think the road had stolen you from us.” “Only tried, sir,” Frederick replied, patting Thunder’s neck. Sir Roland gave the stallion an approving look, then studied Frederick with a grave expression. “Good. The castle has need of brave hearts—and yours will be tested sooner than you expect.” </nc-section>
