<nc-section data-title="Chapter 1: The Stableyard Greeting — Version 1" data-color="red"> Thunder’s hooves slowed from a thunderous gallop to a tired clatter as we passed beneath the castle gate. Beyond the walls lay a broad stableyard, alive with the smells of hay, leather, and woodsmoke. Grooms hurried between stalls while squires wrestled with buckets and bridles. A man in polished, weather-worn armor stood beside the largest stable. His cloak was crimson, though dust had dulled its hem, and a silver wolf was worked into the clasp at his throat. He watched me dismount with eyes as sharp as a hawk’s. “Frederick, I presume,” he said. I straightened, suddenly aware of the mud on my boots and the travel dust on my tunic. “Yes, sir.” The knight’s stern face softened by the smallest degree. “Sir Roland of Ashmere. I oversee the squires of this keep—and, when necessary, teach them the difference between bravery and foolishness.” Thunder snorted behind me, as if he understood. Sir Roland glanced at the stallion, then nodded approvingly. “A fine mount. See that you care for him yourself before you seek food or sleep. A squire who leaves his horse unattended will not last long in my service.” “Yes, Sir Roland.” “Good.” He turned toward the shadowed stable doors. “Then welcome to the castle, Frederick. You have arrived at an interesting time.” </nc-section> <nc-section data-title="Chapter 1: The Stableyard Greeting — Version 2" data-color="green"> The castle swallowed the last of the sunlight as Frederick guided Thunder into the stableyard. Lanterns had already been lit beneath the eaves, their golden glow trembling over rain-dark cobbles. Somewhere within the stables, a horse whinnied nervously. “Easy, lad,” Frederick whispered, patting Thunder’s neck. “You have a calming hand.” Frederick turned. A knight stood near a rack of training spears, half concealed by the long shadows. He was broad-shouldered and gray at the temples, dressed not for ceremony but for work: mail beneath a dark green surcoat, a sword at his hip, and straw caught in one armored boot. “I am Sir Roland,” the man said. “The captain told me to expect a new squire before nightfall. I feared the road had claimed you.” “The road tried,” Frederick admitted. Sir Roland gave a low laugh. “Then it has tested you more gently than I shall.” Despite himself, Frederick smiled. “I am ready, sir.” “Every boy says that at the gate.” Sir Roland stepped closer and studied him—not unkindly, but thoroughly. “Readiness is proven in cold mornings, sore hands, and choices made when no one is watching. Begin with your horse. Rub him down, feed him, and make certain his tack is sound.” Thunder tossed his mane as if in agreement. When Frederick reached for the bridle, Sir Roland added quietly, “And keep your eyes open. There are old things stirring beyond these walls. A good squire must learn to notice what others overlook.” </nc-section> <nc-section data-title="Chapter 1: The Stableyard Greeting — Version 3" data-color="blue"> Frederick rode into the stableyard just as the castle bells began to ring for evening. Thunder’s flanks shone with sweat, and Frederick’s legs ached from the long journey, but he sat as straight as he could beneath the curious stares of the stablehands. Near the stable doors, a knight was helping a young groom lift a sack of oats. He wore no helmet, and his brown hair was tied back at his neck. Though a scar crossed one cheek, his expression was warm when he saw Frederick. “You must be the new arrival,” he called. Frederick dismounted, nearly stumbling as his boots struck the ground. “Frederick, sir. Frederick Vale.” The knight set down the sack and wiped his hands on his cloak. “Sir Roland. I serve this castle, and from tomorrow onward, you will serve beside me.” Frederick bowed quickly. “It will be an honor.” “Perhaps,” Sir Roland said, with a glint of humor in his eyes. “For tonight, it will be an honor if you can keep that magnificent beast from eating half my stable.” Thunder had already stretched his nose toward a nearby bundle of hay. Frederick pulled him back, embarrassed. “He is hungry after the road.” “Then feed him,” Sir Roland replied. “A knight’s first lesson is loyalty. A squire’s first is responsibility. The two are not so different.” As Frederick led Thunder toward an empty stall, Sir Roland looked toward the western horizon, where the final strip of sunlight had faded into violet cloud. “Rest while you can,” the knight murmured. “Tomorrow, we begin.” </nc-section>
