<nc-section data-title="Version 1: A Stern Inspection" data-color="red"> Frederick had barely dismounted Thunder when a shadow fell across the stable yard. Sir Roland, broad-shouldered in dented plate, stood with arms crossed, his grey beard flecked with straw. "So you're the new squire," he rumbled, eyes raking over Frederick's travel-worn cloak and blistered hands. "Stables first, stories later. If you can't tend a horse, you'll never serve a knight." He thrust a curry comb into Frederick's chest. "Well? Show me how Thunder was cared for on the road." </nc-section> <nc-section data-title="Version 2: A Warm Welcome" data-color="green"> The smell of hay and leather filled the stables as Frederick led Thunder inside. A hearty laugh boomed behind him. "Ho! You must be Frederick!" Sir Roland, his face red-cheerful beneath a polished helm, clapped a gauntleted hand on the boy's shoulder. "Welcome to Stonehold, lad. Fine stallion you've got there — Thunder, eh? A fitting name." He knelt to offer the horse an apple, winking up at Frederick. "Come, stable him here beside my old mare, Bess. Then we'll get you bread and stew. Training can wait till morning." </nc-section> <nc-section data-title="Version 3: Shadows in the Straw" data-color="blue"> Dusk pooled deep in the stables when Frederick arrived, leading Thunder into the dim lantern light. Sir Roland was already there, silent among the stalls, brushing down a restless warhorse. He looked up slowly, his eyes pale and tired. "Frederick," he said, as if he had known the name for years. "You came at a strange hour. The dragons have not been seen for a generation, and yet the horses grow nervous each night." He stepped forward and took Thunder's reins. "Leave him with me. Walk carefully in this castle, squire. Old things are waking." </nc-section>
