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: Sir Roland’s Welcome" data-color="red"> Thunder’s hooves slowed from a gallop to a proud, stamping walk as Frederick passed beneath the castle’s raised portcullis. The stable yard lay beyond, warm with the smell of hay, leather, and woodsmoke. A broad-shouldered knight stood beside the open stable doors, his silvered breastplate catching the last red light of evening. “Frederick, I presume,” the knight called. Frederick swung down from Thunder’s saddle, suddenly conscious of the dust on his boots and the travel stains upon his cloak. “Yes, sir.” The knight smiled beneath his trimmed dark beard. “Then welcome to Greywatch. I am Sir Roland, knight of these lands—and, for the moment, the man responsible for seeing that you do not fall off a horse, lose a sword, or get eaten by anything in the forest.” A laugh escaped Frederick before he could stop it. Sir Roland took Thunder’s reins with an experienced hand. The stallion lowered his head, strangely calm. “A fine mount,” Roland said. “And a fine beginning. Come. Your training starts at dawn, but tonight you may eat like a guest of the castle.” As they entered the stables, Frederick glanced back toward the darkening hills. For a heartbeat, he thought he saw a vast shadow pass across the clouds—wings against the dying sun. </nc-section> <nc-section data-title="Version 2: The Knight at the Stable Door" data-color="green"> The castle yard echoed with the ring of Thunder’s iron shoes. Frederick guided the stallion toward the stables, where lanterns had just been lit beneath the eaves. Their gold light spilled across the packed earth. A knight waited there, leaning against a weathered post. He wore no helmet, only a deep green cloak over chainmail, and a scar crossed one eyebrow like a pale bolt of lightning. “Easy there,” he said as Thunder snorted and tossed his mane. His voice was low, but it carried the quiet authority of someone accustomed to being obeyed. Frederick dismounted. “Good evening, sir.” “Sir Roland,” the man replied. He offered Frederick his forearm rather than a courtly bow. “I knew your father, years ago. He said you were stubborn, brave, and far too curious for your own safety.” Frederick clasped the knight’s arm, embarrassed and pleased. “He said that?” “He did.” Roland’s expression softened briefly. Then he looked toward the eastern mountains, whose peaks were swallowed by night. “Those qualities may serve you here. Greywatch has need of young men who can be brave. More need than it has had in a very long time.” Thunder gave a nervous whicker. Sir Roland noticed. “Stable him well,” he told Frederick. “Tomorrow, I will show you why the ravens no longer fly over the old ruins.” </nc-section> <nc-section data-title="Version 3: A Warning in the Twilight" data-color="blue"> Frederick rode into the stable yard just as the last strip of sunlight vanished behind the castle towers. Thunder’s breath steamed in the cooling air. Stablehands hurried past with buckets and armfuls of hay, but one figure remained still amid the bustle. He was a knight, tall and straight despite the years marked upon his face. A blue cloak hung from his shoulders, fastened with a brooch shaped like a dragon’s claw. “You must be Frederick,” he said. Frederick slid from the saddle and bowed awkwardly. “I am, sir.” “Sir Roland.” The knight’s eyes rested on Thunder, then on the worn travel pack behind Frederick’s saddle. “You arrived quickly. That is fortunate.” “Fortunate, sir?” Roland did not answer at once. Instead, he reached up and touched the dragon-claw brooch at his throat. “There are old stories told in this kingdom,” he said. “Most are harmless. Stories for children and fools.” His gaze moved to the black silhouette of the distant mountains. “But some stories remember themselves.” A cold shiver ran through Frederick, though the stable yard was warm with horses and lanternlight. Sir Roland took Thunder’s reins. “Bring your things inside. You will have a room in the eastern tower.” He paused, and his voice grew quieter. “And if you hear wings in the night, Frederick, do not go looking for their source.” Frederick watched the knight lead Thunder into the shadows of the stable, wondering why a man like Sir Roland sounded afraid. </nc-section>
