<nc-section data-title="A Stern Welcome" data-color="red"> As I dismounted, a tall knight in burnished armor strode from the shadows of the stable. Sir Roland's eyes were sharp as flint, and his voice carried the weight of command. "You're the new squire? Late, and your horse is lathered. Groom him properly before you even think of entering the keep." I bowed hastily, shame prickling my neck, but beneath his harsh words I caught a flicker of appraisal—like he was measuring more than my posture. </nc-section> <nc-section data-title="A Kindred Spirit" data-color="green"> Before my boots even touched the cobblestones, a hearty laugh rang from the stable door. Sir Roland emerged, sleeves rolled and straw in his hair, smelling of hay and leather. "Frederick! By the look of Thunder's fine lines, you've cared for him better than most knights care for their own mounts." He clapped my shoulder, his grin crinkling sun-weathered cheeks. "Come, let's get this noble beast watered. We'll speak of your training over a pail of oats." </nc-section> <nc-section data-title="A Whisper of Destiny" data-color="blue"> I had barely drawn rein when Sir Roland appeared, silent as an owl, his silvered cloak blending with the gloaming. He spoke low, almost a chant. "Your coming was written in the stars, Frederick. The Last Dragon stirs, and the threads of fate draw tight around this castle." He placed a gloved hand on Thunder's neck, and the stallion shivered. "You will learn more than swordplay here. Tonight, seek me by the old well—there is much you must understand before the moon wanes." </nc-section>
