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 Stern Welcome" data-color="red"> I reined Thunder to a snorting halt beside the stable yard's worn cobbles. Sir Roland stood with arms crossed, steel-gray eyes measuring me like a blade finds a flaw. "You're late, boy. The sun's nearly gone, and the horses don't wait for wandering squires." A stable hand took Thunder's reins, but Sir Roland didn't move. "Get him brushed and watered, then find me in the armory. You'll not be served supper until your saddle is clean." I swallowed. So this was my welcome. </nc-section> <nc-section data-title="Version 2: The Warm Welcome" data-color="green"> I eased Thunder to a walk as the stable's warm lantern light reached across the yard. Sir Roland stepped out from the shadow of the gate, and to my surprise, he was smiling. "Frederick! You've made good time, lad. That stallion's got fire in him—what's his name?" He took Thunder's bridle himself and led us inside, his voice easy. "The castle can wait. Let's get your horse settled first, then we'll find you a hot meal and a dry bed." I felt the day's tension leave my shoulders. </nc-section> <nc-section data-title="Version 3: The Ominous Welcome" data-color="blue"> I brought Thunder to a stop near the stables, where Sir Roland stood motionless, his cloak stirring in a wind I couldn't feel. He did not smile. "Frederick," he said, and his voice was low, as if the stones themselves might listen. "You've arrived at a strange hour. Did you see anything on the road? Any shadow that did not belong to a bird?" I shook my head. He glanced toward the mountains, where the last light bled red across the peaks. "Good. Keep it that way. Now get that horse inside, quickly, and speak of this to no one." </nc-section>
