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: The Knight's Inspection" data-color="red"> Frederick dismounted by the stable yard, his legs shaking from the long ride, and led Thunder toward the troughs. Before he could find a groom, a man in dented plate armor stepped from the shadows of the stable, a scar running through his beard. "You must be the new squire," Sir Roland said, not as a question but as a judgment. He looked Frederick up and down, taking in the mud on his boots and the worn strap of his pack. "I am Sir Roland, knight of this keep. You will serve under my eye for the first month. That means mucking stalls before dawn, polishing mail until you can see your face in it, and keeping your mouth shut unless spoken to." Frederick bowed so quickly he nearly dropped Thunder's reins. "Yes, sir. I mean — thank you, sir." Roland took Thunder's bridle with a gloved hand and led the stallion himself, testing Frederick with a hard stare. "The last boy who came here thought the stables were a place to rest. He left on foot a week later. Do you understand?" "Yes, sir," Frederick said, his heart hammering. "Good. Unpack your things in the loft above the hay. Then report to the armory." Roland turned away, his armor clanking like a bell. "And Frederick — in this castle, we greet a knight by standing straight, not trembling."</nc-section> <nc-section data-title="Version 2: A Warm Welcome" data-color="green"> The stable yard smelled of warm hay and horses, and Frederick was still catching his breath from Thunder's gallop when a broad-shouldered knight came striding out with a bucket in each hand, whistling a tune. "Ho there! Mind the bucket, lad," he laughed, stepping aside with surprising lightness for a man in full armor. "You must be Frederick. I'm Sir Roland. Welcome to the finest — and muddiest — keep in the kingdom!" Frederick, startled, almost dropped his saddlebags. "Sir! I — yes, sir, that's me." "Then let me help you before that poor horse decides he's had enough of your riding," Sir Roland said with a grin, taking the reins and giving Thunder a familiar pat on the neck. "He's a fine animal. Spirit like that needs a gentle hand, not a heavy one." He showed Frederick where to rub Thunder down, where the water was hauled from, and where the other squires snuck extra bread from the kitchen. "Rule one of the stables," he said, clapping Frederick on the shoulder, "is never greet a horse before you've greeted the stable boy. Rule two is, if you need anything, you ask. We look after our own here." By the time the sun set, Frederick had been fed, shown to a clean loft bed, and given a spare cloak by a knight who seemed more like a kindly uncle than a lord of war.</nc-section> <nc-section data-title="Version 3: Warning at Dusk" data-color="blue"> Twilight had fallen by the time Frederick reached the stables, and the yard was quiet except for the low sounds of horses shifting in their stalls. A single lantern burned by the far gate, and in its light stood an older knight, his helm under his arm, his face half-hidden in shadow. Sir Roland did not smile. "Frederick of nowhere," he said quietly, his voice low enough that the horses stirred. "You came on the north road, did you not? Did you see any tracks? Smoke?" Frederick shook his head, confused. "No, sir. Only fields and—" "Good. Pray none find you." Roland stepped closer, and Frederick saw the deep, silvery burn scar that twisted up the side of his neck. He stared, not at Frederick, but at Thunder, who had gone still and wide-eyed in the gloom. "That horse knows something," Roland muttered, almost to himself. Then, to Frederick, louder: "I greet you near the stables because a squire must learn first where the danger sleeps. Beyond the north wall, the forest has been silent for three nights. No birds. No wolves." He placed a cold, gauntleted hand on Frederick's shoulder. "Sleep in the loft tonight. Keep your dagger close. And if you hear wings over the keep..." Roland paused. "If you hear wings, boy, do not look up."</nc-section>
