When I Was Reincarnated, I Was a Dragon. Now That I’m a Dragon, I’m Going to Build My Own Castle

I was reincarnated as a dragon. Well, I was still a young dragon, but now I’m officially becoming a full-fledged dragon. Becoming a mature dragon is all well and good, but what to do now? I’m not particularly interested in finding a mate. However, I do need to decide where to live. It would probably be good to have some interaction with human settlements. Maybe I should dig a cave at the foot of a mountain near a human settlement to live in. Well, who knows what will happen from here on out.
