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 Gruff Trial" data-color="red"> Frederick swings down from Thunder’s saddle, his scuffed leather boots hitting the stable yard cobblestones hard enough to send a skitter of pebbles across the ground. Before he can even loop Thunder’s reins around the hitching post, a broad shadow falls over him, and Sir Roland steps out from the stable’s archway, a crumpled gauntlet clutched in one calloused hand, a jagged scar splitting his left eyebrow. “You’re late, squire,” the knight barks, his voice rough as millstone grit. He prods Thunder’s front left hoof with the tip of his boot, and Frederick flinches—he’d noticed the stone stuck in the stallion’s hoof an hour back, but pushed on to outrun the dusk storm brewing on the horizon. “You think the king’s army tolerates squires who neglect their mounts before they even cross the threshold? Tend to that hoof. Then report to the barracks. If you’re not done in ten minutes, you’ll go without supper for a week.” </nc-section> <nc-section data-title="Version 2: The Long-Awaited Welcome" data-color="green"> Frederick reins Thunder in to a slow amble as he reaches the stable yard, the stallion’s hooves thudding soft on moss-fringed cobblestones, and a warm laugh rings out from the stables’ wide oak doors. Sir Roland leans against the frame, a crinkled leather sack of apples in one arm, his silver lion-emblazoned surcoat unblemished, his face soft with a smile Frederick recognizes from his father’s old war stories. “Frederick, lad! I’ve been waiting an hour for you—saved the sweetest apples for your Thunder, I remember how that beast would steal my entire stores when your father brought him here as a colt.” The knight pushes off the doorframe to clap Frederick on the shoulder hard enough to make him grin, and nods toward the castle’s kitchen wing, where the scent of spiced beef and honey cake drifts on the wind. “Leave the reins to the stable boys, come warm up. I’ve got a mug of spiced cider that’s been steeping since midday.” </nc-section> <nc-section data-title="Version 3: The Coded Warning" data-color="blue"> Frederick slips down from Thunder’s saddle, his hand drifting to the hilt of the small dagger at his waist as he scans the unnaturally quiet stable yard—no stable boys, no clatter of water buckets, just the distant hoot of an owl. A man steps out from the shadow of a hayloft: Sir Roland, his dark armor streaked with a black residue that glints faint even in the dusk, his voice low enough only Frederick can hear as he crosses the yard. “The wildfire burns in the west,” the knight says, the exact code phrase Frederick’s mother had pressed into him the day he left home, the signal that the realm’s hidden spy network was waiting for him. Sir Roland glances over his shoulder, as if expecting guards to round the corner at any moment, and slips a cold iron key into Frederick’s palm before he can speak. “Don’t trust anyone in this castle but me. The last squire who arrived here didn’t live long enough to begin training. The last dragon’s egg is hidden somewhere in these walls, and half the court would kill to get their hands on it.” </nc-section>
