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 Thunder to a halt beneath the shadow of the castle wall. The stallion snorted, stamping at the unfamiliar scents of hay, leather, and iron. A broad-shouldered knight stepped from between the stalls, his crimson cloak fastened with a silver dragon. His hair was streaked with gray, but his eyes were sharp and watchful. “You must be Frederick,” he said. Frederick dismounted quickly and bowed. “Yes, sir.” “I am Sir Roland, master of the castle’s squires.” Roland glanced at Thunder, then back at the boy. “You’ve arrived late.” “The road was longer than I expected.” “Roads are often longer when one is running from something.” The knight’s gaze lingered on him. “Bring your horse inside. Supper is nearly over, and tomorrow your training begins.” As Frederick led Thunder toward the stable, a deep rumble rolled beneath the earth. Every horse reared in alarm. Sir Roland’s hand fell to his sword. From the distant mountains came a cry unlike anything Frederick had ever heard—a roar vast enough to shake the evening sky. </nc-section> <nc-section data-title="Version 2" data-color="green"> Frederick found the stables tucked beside the eastern tower, where lanterns glowed warmly against the gathering dusk. Before he could dismount, a knight in a weathered green surcoat approached, carrying a bucket of oats. “Easy there,” the knight said to Thunder. “The castle has seen stranger arrivals than you.” Frederick blinked. “You know my horse?” “No, but I know a nervous animal when I see one.” The knight set down the bucket and offered his hand. “Sir Roland.” Frederick shook it. Roland’s grip was firm but kind. “Frederick, my lord sent word that you were coming. He says you show promise.” “Did he say anything else?” “That you are stubborn, undertrained, and willing to learn.” Roland smiled faintly. “A useful combination, if properly managed.” Inside the stable, Thunder suddenly turned toward the far wall and began to paw at the straw. Frederick pulled it aside, revealing a blackened scale half-buried in the dirt. Sir Roland’s expression changed. “Put that back,” he whispered. “But what is it?” The knight looked toward the darkening mountains. “Something that should have remained dead.” </nc-section> <nc-section data-title="Version 3" data-color="blue"> By the time Frederick reached the stables, the last light had faded from the sky. Snowy peaks gleamed beyond the battlements, and the castle’s blue banners snapped sharply in the cold wind. A knight waited beside the stable doors, tall and lean beneath a fur-lined cloak. His polished helm rested under one arm. “Frederick?” he called. “Yes, sir.” “Sir Roland.” He nodded toward Thunder. “A fine stallion. He’ll need a stronger stall hand than you, if you plan to keep him from biting everyone in the kingdom.” Frederick managed a nervous smile. “He only bites strangers.” “Then we shall become acquainted quickly.” Roland led them into the stable. As Frederick began removing Thunder’s saddle, he noticed a strange blue light flickering beneath the horse’s mane. The glow vanished when he touched it. Sir Roland saw it too. “Did you feel that?” Frederick asked. The knight’s face had gone pale. “No.” A bell began ringing from the highest tower—not the hour bell, but the alarm. Across the courtyard, soldiers rushed to the walls. Roland seized his sword and thrust a lantern into Frederick’s hands. “Stay here.” “What’s happening?” The knight looked toward the mountains, where a single star burned brighter than the rest. “The dragon-fire has returned.” </nc-section>
