<nc-section data-title="Section 5.1" data-color="red"> Sir Roland awaits Frederick by the stables, his armour flashing like molten copper beneath the sunset. He clasps young Frederick's forearm with a warrior's warmth and intones, "Steel your heart, lad—the true trials begin beyond these stables." </nc-section> <nc-section data-title="Section 5.2" data-color="green"> Sir Roland leans against the stable door, sunlight turning the moss beneath his boots to emerald. With a broad grin, he says, "You've come far already, Frederick. Here, the horses teach patience; tomorrow, the blade will test valor." </nc-section> <nc-section data-title="Section 5.3" data-color="blue"> Dominating the stable yard like a living banner, Sir Roland dips his head in greeting, eyes steady as sapphire. He murmurs, "The kingdom's fate rides with those who serve it—walk with me, Frederick, and learn what it means to guard the last dragon's legacy." </nc-section>
