<nc-section data-title="Version 1" data-color="red"> Frederick had barely dismounted from Thunder near the stables when a broad-shouldered knight in polished steel approached, his grey beard neatly trimmed. "You must be Frederick," he said, his voice gruff but kind. "I am Sir Roland, keeper of this castle's knights. I see you have arrived just in time for evening drills. Stable your horse, squire, and come - there is much for you to learn." </nc-section> <nc-section data-title="Version 2" data-color="green"> The smell of hay and horses hung heavy around the stables as Frederick led Thunder inside. An older knight was already waiting there, leaning against a post with arms crossed, his cloak bearing the faded crest of a rearing lion. "So, you're the new squire we've been expecting," Sir Roland said with a warm chuckle, stepping forward to clasp Frederick's shoulder. "Welcome to Castle Ironhold, lad. Leave your stallion to the stablehands. You've had a long ride." </nc-section> <nc-section data-title="Version 3" data-color="blue"> Near the stables, where squires were brushing down warhorses after the day's patrol, Frederick was met by a tall figure. Sir Roland removed his helm, revealing a stern face softened by a welcoming smile. "Frederick, I presume?" the knight called out. "I am Sir Roland. Lord Alistair sent word of your coming. Come, let us get you settled - the road is weary, and your training begins at dawn." </nc-section>
