<nc-section data-title="Chapter 2: A Stern Welcome - Version 1" data-color="red"> As I dismounted from Thunder, a gruff voice called out from the shadows of the stable. "Another fresh-faced squire, I see." Sir Roland emerged, his armor bearing the scars of countless battles. His weathered face was stern, eyes sharp as flint. "Welcome to the castle, boy. I trust you've come prepared to work harder than you've ever worked in your life. The training ahead will test every fiber of your being. Drop your belongings in the bunkhouse and report back here within the hour. We begin at dawn." He turned sharply and walked away, leaving no room for questions. </nc-section> <nc-section data-title="Chapter 2: An Unexpected Alliance - Version 2" data-color="green"> A warm smile greeted me as a tall knight with kind eyes approached from the stable entrance. "Frederick, is it? I am Sir Roland, master of the guard here at the castle." He extended his hand in genuine welcome. "I've heard much about your family's lineage from the king himself. You come from good stock. Come, let me show you to the stables properly—Thunder here looks like a fine animal. I keep my own mount just down the way, a mare named Starlight. Perhaps our steeds will become companions, as I hope we shall as well." His warmth immediately eased the anxiety that had gripped my chest. </nc-section> <nc-section data-title="Chapter 2: The Test Begins - Version 3" data-color="blue"> Before my feet had fully touched the ground, a shadow fell across my path. Sir Roland stood between me and the stable doors, his expression unreadable. "So, you're the squire everyone's been whispering about," he said, circling me slowly like a predator assessing prey. "They say you have potential. They say you might be different." He paused, studying my face intently. "Potential means nothing here. Only action matters. Tell me, Frederick—why did you really come to this castle? What do you seek?" His penetrating gaze seemed to look through me, as if searching for the very truth of my soul. </nc-section>
