Yeah, but Aden did that after they pretty much dared him to. At least by dragon standards. Folks forget that wiping out a city is mild, by dragon standards. And all told, it looks like Sirrug had a higher body count over the years. Aden just leveled Tehran. Sirrug went hunting people, and kept taking out more than just the guy he was hunting. A friend of mine said the dragons engineered the fall of the US because they were the only government at the time capable of taking out a dragon. I guess Aztlan decided to step up into the big-boy shoes. Now, if they weren't owned lock, stock and barrel by the Mexican drug cartels.
