The story of a semi-benevolent dragon who occasionally does the right thing for the wrong reasons. Protecting villagers from marauding soldiers? Of course. They can't give tribute if they're dead or their crops are on fire! Destroying a tyrannical kingdom? Absolutely. They have treasure... that could be his treasure.
