### Version 1 (Red) <nc-section data-title="The Knight's Warning" data-color="red"> The heavy iron gates groaned as they swung open, revealing the sprawling courtyard of Blackthorn Castle. I dismounted Thunder with a thud, my boots kicking up dust from the cobblestones. Before I could take another step, a shadow loomed over me. "Halt, squire!" boomed a voice. I turned to see a knight clad in scarlet armor, his visor lifted to reveal a grizzled face framed by a wild, red beard. His cloak, embroidered with the sigil of a burning phoenix, billowed behind him as he strode forward. One hand rested on the hilt of his sword, the other shielding his eyes from the setting sun. "Sir Roland," I stammered, bowing low. "I am Frederick, newly arrived to begin my training." His piercing gaze raked over me, from my dusty boots to the nervous twitch in my fingers. "Newly arrived, eh?" he grunted. "You’re late. The evening meal’s nearly done." Before I could stammer an apology, he leaned in, his voice dropping to a growl. "Listen well, boy. This castle holds more than just armor and ale. There are things in these halls—things that hunt after dark." He tapped his sword. "Keep your wits about you, and don’t wander the upper towers." My stomach twisted. “What—what kind of things?” Sir Roland’s grin was sharp as a blade. "That’s why you’re here, isn’t it? To find out." He clapped me on the shoulder, nearly knocking me off balance. "Welcome to Blackthorn." </nc-section> --- ### Version 2 (Green) <nc-section data-title="A Familiar Face" data-color="green"> The courtyard smelled of hay and roasted meat, the aroma pulling me toward the stables like a magnet. Thunder nuzzled my shoulder as I patted his neck, whispering, "We made it, old friend." Suddenly, a familiar laugh cut through the evening air. "Well, if it isn’t the squire who nearly fell off his horse on the road!" I spun around to see a knight lounging against the stable door, his green surcoat emblazoned with the crest of the Blackthorn stag. His dark hair was tousled, and a playful smirk tugged at his lips. Relief flooded through me—it was Sir Elias, the knight who had escorted me partway on my journey. "Sir Elias!" I grinned. "I didn’t know you were stationed here." He pushed off the door and clapped me on the back. "And miss the chance to tease you some more? Never." His eyes twinkled with amusement as he nodded toward the castle’s great hall, where laughter and clinking cups echoed. "Come on, then. You look like you could use a proper meal—and more than a few explanations about why you’re here." As we walked, I caught him glancing at my sword belt. "No sword, eh?" I swallowed. "Not yet. They said I’d earn one." Sir Elias chuckled. "Patience, lad. In Blackthorn, your first lesson might be learning when—and when *not*—to draw steel." </nc-section> --- ### Version 3 (Blue) <nc-section data-title="The Weight of Expectations" data-color="blue"> The castle loomed before me, its obsidian towers piercing the twilight sky like claws. Thunder’s hooves echoed hollowly against the drawbridge as we crossed the moat, the water below dark and still. My palms were slick with sweat despite the evening chill. Then, without warning, a hand clamped onto my shoulder. I flinched and turned to see a knight in polished blue armor, his face obscured by a visor etched with silver filigree. A long mantle of cobalt silk draped over his shoulders, embroidered with the royal crest—a dragon coiled around a sword. "Frederick of Eldermere," he said, his voice measured but firm. "I am Sir Aldric, master of the guard." I swallowed hard. "Y-yes, sir. At your service." His gloved fingers tightened slightly. "No words of false humility," he commanded. "You stand in Blackthorn now. This is no ordinary fortress—it is the last bastion between the known world and the... *others*." His gaze darkened. "The Dragon Cult stirs in the north. Their spies could be among us." My pulse quickened. "Dragon Cult?" He ignored my question, instead studying me with cold intensity. "You are here for a reason. Prove it was not wasted." With that, he released me and stepped back. "Go. Rest. Tomorrow, your real training begins." As he turned to leave, I caught one last, chilling whisper on the wind: "And Frederick? Watch the skies." </nc-section>
