<nc-section data-title="The Greeting: Version 1" data-color="red"> As I dismounted near the bustling stables, the heavy scent of straw and horseflesh filling the air, a figure emerged from the shadows of an archway. He was a man of imposing stature, clad in a practical, unadorned gambeson, his greying hair cropped short. Sir Roland, I presumed, loomed over me, his gaze sharp yet not unkind. "You're Frederick, then?" His voice was a low rumble, like distant thunder, cutting through the whinnies of the horses. "You've made good time, boy. Welcome to Blackwood Keep." </nc-section> <nc-section data-title="The Greeting: Version 2" data-color="green"> I led Thunder towards an empty stall, loosening his cinch, when a hearty laugh echoed through the stable yard. A broad-shouldered knight, his face etched with the lines of sun and battle, approached with an easy stride. His surcoat, though worn, bore the crest of the local lord. "Ah, the new squire!" he boomed, extending a calloused hand. "Sir Roland, at your service. Don't worry, lad, your steed will be well cared for. And you look like you could use a warm meal and a soft bed more than another minute in that saddle." He clapped me on the shoulder, a friendly, surprisingly gentle force. </nc-section> <nc-section data-title="The Greeting: Version 3" data-color="blue"> I was just leading Thunder into the dim interior of the stables, the sounds of grooming and soft snorts surrounding me, when a presence solidified at my side. A knight, clad in gleaming, well-maintained plate over a dark tunic, stood with quiet authority. His face was stern, his eyes observant, but carried no malice. "Squire Frederick, I presume?" His voice was measured, formal. "I am Sir Roland, Knight of Blackwood. We were expecting you. Leave your horse; a stable hand will see to him. Come, there is much to discuss regarding your duties." He gestured towards the castle's inner courtyard, his gaze assessing. </nc-section>
