<nc-section data-title="A Stern Welcome" data-color="red"> As I reined Thunder toward the stables, a knight in scarred plate armor stepped from the shadow of the gatehouse. His hand rested on the hilt of his sword, not quite a threat, but a reminder. "You're the squire?" Sir Roland’s voice was gravel over steel. His eyes swept over me like a tally of deficits. "Stable your horse and report to the training yard at dawn. Late, and you'll wish you'd stayed in whatever village whelped you." He turned away before I could reply, the clank of his boots leaving no room for argument. </nc-section> <nc-section data-title="A Warm Council" data-color="green"> As I guided Thunder toward the welcoming scent of hay and horses, a knight with a sun-browned face emerged from the stable door, dusting straw from his tunic. "Frederick, I presume?" Sir Roland’s smile carved friendly lines around his eyes. "I saw your approach from the tower. You ride well—your father would be proud." He took Thunder’s bridle gently. "Come, I’ll show you the stalls and then the kitchens. A hot meal awaits any lad brave enough to chase knighthood." </nc-section> <nc-section data-title="A Measured Judgement" data-color="blue"> By the time I reached the stables, twilight had seeped into the courtyard. Standing beside the water trough was a knight with a calm, measured gaze—Sir Roland, I knew, from the silver falcon on his shoulder. "You made good time," he said, his voice soft as rain on stone. He studied Thunder with an appraiser’s eye, then nodded once. "There’s a stall prepared. Settle him in, then find me in the great hall. We have much to discuss, but no need to rush. The night listens better than it speaks." He turned with a fluid grace, expecting me to follow. </nc-section>
