<nc-section data-title="The Greeting: Version 1" data-color="red"> I guided Thunder towards the bustling stables, the scent of hay and horseflesh thick in the air. As I dismounted, my legs stiff from the long ride, a figure emerged from the shadows of the stable archway. He was a man of imposing stature, his broad shoulders filling out the worn steel of his breastplate, and a grizzled beard framed a face etched with the lines of countless battles. "Squire Frederick, I presume?" His voice was a low rumble, direct and uncompromising. "I am Sir Roland. Welcome to Castle Valoria. Your training begins now." </nc-section> <nc-section data-title="The Greeting: Version 2" data-color="green"> Steam rose from Thunder's flanks as I led him into the stable yard, the clatter of hoofs and the murmur of stablehands filling the twilight. Before I could even secure my mount, a tall knight with hair the color of salt and pepper stepped forward, a kind yet firm smile on his face. He wore practical, unadorned armor, and his movements were those of a man perpetually ready. "Frederick, is it?" he asked, extending a gauntleted hand. "Sir Roland. Good to finally have you. Leave your horse to the lads, and come, let's get you settled before we discuss the arduous path ahead." </nc-section> <nc-section data-title="The Greeting: Version 3" data-color="blue"> The moment Thunder's hoofs echoed on the cobbles of the stable yard, a stern-faced knight in chainmail and a crimson surcoat approached, his expression unreadable. He was lean, hawk-nosed, and his eyes, though sharp, held a weariness that spoke of long service. "You are Frederick," he stated, rather than asked, as I untethered my saddlebags. "I am Sir Roland, the castle's resident blade-master. Your arrival was expected. Hand your horse to the stable master, and then report to the training grounds. We waste no daylight, even at dusk." </nc-section>
