<nc-section data-title="The Greeting at the Stables - Version 1" data-color="red"> Thunder had barely stopped steaming when a broad-shouldered man in a dented breastplate stepped from the stables, wiping his hands on a rag. His beard was more grey than brown, but his eyes were sharp. "You must be Frederick," he said, his voice like gravel rolling in a barrel. "I'm Sir Roland. Stable master said we'd have another squire who thinks a horse is just for looking pretty." He eyed Thunder, then me, and gave a short, approving nod. "You rode him hard but not cruel. That's a start. Come on, lad. Let's get him brushed, and then I'll show you where you'll be sleeping. Training starts before dawn." </nc-section> <nc-section data-title="The Greeting at the Stables - Version 2" data-color="green"> Near the stables, a knight was waiting. He was not in full ceremony plate, but in simple, well-kept chain and leather, his surcoat bearing the faded sigil of a white oak. "Squire Frederick?" he called as I dismounted. "Welcome to Caerlin Keep." He stepped forward and offered his hand, clasping my forearm in the warrior's grip. "I am Sir Roland. Lord Eddric charged me with your training. Your letter said you came from Lowfield - good, strong folk there. Leave your things, see to your horse first. A squire who cares for his mount before himself is one I can work with." Behind him, the stable doors stood open, warm with the smell of hay and horses. </nc-section> <nc-section data-title="The Greeting at the Stables - Version 3" data-color="blue"> I was just leading Thunder toward the stables when I heard a laugh. "By the gods, they send them younger every year!" Leaning against a post, arms crossed, was a tall knight with a kind, sun-weathered face. He pushed off and walked over, taking Thunder's reins from me before I could protest and running a practiced hand along the stallion's flank. "You are Frederick, yes? I am Roland. You'll forgive me if I don't kneel - my knees are still angry about the last tourney." He grinned at me, and suddenly the great, intimidating castle felt a little less cold. "Come with me, young Frederick. We'll water your friend here, and I'll get you some supper. You have stories to tell, and I have a feeling your training will give us plenty more." </nc-section>
