An old man with grizzled hair opened the door. When he saw Merlin, a puzzled look crossed his face as he asked softly, "Who are you looking for?"
"May I ask if Heroult stays here? I'm Mr. Heroult's friend. My name is Leon. I believe Mr. Heroult knows me."
Merlin declared his identity. This unfamiliar old man sized Merlin up and then said, "Please hold on a moment. I'll ask for Sir Heroult."
It looked like this Heroult had quite a status. After all, though this castle was relatively old, it was naturally quite impressive to own such a massive castle in the Holy Dragon City where land prices were steep.
After a moment, a booming laugh came from within the castle. "Haha, is that Master Leon? You've actually come to the Holy Dragon City."
