<nc-section data-title="The Greeting: Version 1" data-color="red"> Thunder skidded to a halt, hooves churning the dirt as a shadow fell over me. Sir Roland stood by the stable doors, his plate armor dulled by grease and the remnants of a hard day's patrol. His face, etched with jagged scars, twisted into a cynical sneer. "A squire who arrives at dusk is a squire who likes to skip chores, boy," he barked, his voice like grinding gravel. He tossed a rusted pitchfork toward my feet, the metal biting into the mud. "Welcome to hell. Start with the stalls, and if I see a speck of filth come morning, you’ll be sleeping in the muck with the swine." </nc-section> <nc-section data-title="The Greeting: Version 2" data-color="green"> As I dismounted, the scent of fresh hay and oiled leather washed over me. Sir Roland moved from the stable archway with a grace that belied his massive frame. He placed a heavy, gauntleted hand on my shoulder, his expression one of measured appraisal. "You’ve made good time, Frederick," he said, his voice calm and resonant. "The stables are the heart of a knight's life; here, you will learn the temper of your beast and the humility of service. Come, leave your stallion with the groom. There is much to discuss before the moon rises." </nc-section> <nc-section data-title="The Greeting: Version 3" data-color="blue"> The courtyard was bathed in twilight as Sir Roland approached, wiping his hands on a crimson rag. He didn't look like a hero of legend, but rather a weary man burdened by far too much history. He studied me for a long moment, his eyes lingering on the crest embroidered on my tunic. "Squire," he acknowledged with a curt nod. Behind him, the stable doors creaked open, revealing the dim interior. "You’ve come to learn the way of the sword, but you’ll find that the steel demands more than just strength. Tonight, you tend to the horses. Tomorrow, we see if you have the soul to survive what’s coming." </nc-section>
