Hm. I suppose it would be different for a dragon living alone. The dragons I knew, they each had their own caves, but they were all connected by tunnels and there were communal areas in between. Not exactly easy or safe to navigate, so anyone who wasn't familiar with them would be at a severe disadvantage. I wouldn't call Kazul's caves 'cramped'... But then, I'm not a dragon, so I suppose I can't judge.
Sorry, I'm being rude. I'm Princess Cimorene. Until very recently, I was Kazul's princess. She's a dragon. King of them now, back home.
