<nc-section data-title="Chapter 1: The Arrival (Version 1)" data-color="red"> Thunder’s hooves echoed on the cobbles as Sir Roland emerged from the stables, dust clinging to the hem of his crimson cloak. “Steady now, lad,” he said, fixing Frederick with a hawk-like stare. “The king’s stables demand respect—and so do I. Hand Thunder over and follow me; your first lesson begins before the bell tolls.” </nc-section> <nc-section data-title="Chapter 1: The Arrival (Version 2)" data-color="green"> A broad-shouldered knight in forest-green surcoat stepped away from the low stone trough. “You must be Frederick,” Sir Roland declared, wiping his palms on a well-worn towel. “I’ve prepared the corner stall for Thunder. Come; the grooms will tend him while we discuss your responsibilities in the training yard at dawn tomorrow.” </nc-section> <nc-section data-title="Chapter 1: The Arrival (Version 3)" data-color="blue"> Sir Roland’s polished armor flashed cobalt in the twilight as he strode forward from the archway beside the stables. A confident smile softened his weathered face. “Greetings, Frederick. I am Sir Roland, master of the squires. Leave your steed in my care for tonight; tomorrow we ride before sunrise to learn the perils of the eastern road.” </nc-section>
