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="Version 1" data-color="red"> Near the stables, Frederick drew rein beneath the shadow of the castle wall. A broad-shouldered knight stepped from the lantern glow, his silver armor dulled by years of travel. “Frederick?” the knight called. “Yes, sir.” “I am Sir Roland, keeper of these grounds.” His gaze flicked to Thunder, then back to the young squire. “A fine horse—but remember, a brave rider is judged by how he treats his mount.” Frederick dismounted and bowed. Before he could answer, a deep tremor rolled beneath the earth. The stable doors rattled, and every horse within began to scream. Sir Roland’s expression hardened. “You arrived at an ill-fated hour, boy. Come. We must find out what has awakened beneath the castle.” </nc-section> <nc-section data-title="Version 2" data-color="green"> Frederick guided Thunder between the rows of stalls, where the warm scent of hay mingled with smoke from the evening cook fires. A knight in a green cloak waited beside the stable doors, one hand resting on the pommel of his sword. “Welcome to Castle Asterfall,” he said. “I am Sir Roland.” Frederick climbed down and offered a respectful bow. “I am honored, sir.” “Honor is earned here.” Sir Roland studied him for a moment, then handed him a wooden bucket. “Your first lesson begins with the horses. Fill that at the well.” Frederick accepted it, though his arms ached from the journey. As he turned away, Roland added quietly, “And if you hear singing from the western tower, do not answer it.” The young squire glanced toward the darkening battlements. “Why not?” Sir Roland looked toward the moonless sky. “Because nothing human sings there anymore.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> At the edge of the stables, Frederick found a knight waiting beneath a blue-and-silver banner. His weathered face was stern, but his eyes held a spark of welcome. “Frederick of the eastern road?” he asked. Frederick dismounted. “Yes, Sir.” “Sir Roland,” the knight replied, clasping his forearm. “You are late.” “I rode as quickly as I could.” “I know. The ravens warned us that the roads were closing.” Roland glanced past him toward the distant hills, where a thin column of black smoke stained the twilight. “Did you see anything on your way?” Frederick hesitated. Hidden inside his saddlebag was the strange red scale he had found beside the road—a scale that had pulsed with faint heat. “Nothing unusual,” he said. Sir Roland’s gaze lingered on the bag. “Then let us hope the thing that followed you remains in the forest.” Behind them, something enormous breathed in the darkness beyond the stable wall. </nc-section>
