Golden Dragons are a type of dragon that enjoys playing games in the human world. They like to disguise themselves as minstrels with little power, weak wandering mages, or even beautiful women.
In short, Golden Dragons enjoy transforming into forms that can entice humans to commit crimes. After drawing in those who wish to commit such wrongdoings, they would then reveal their true form and educate these evildoers. Whether this education is physical or psychological, depends on the circumstances.
Summarily, Golden Dragons are very fond of a kind of bait-and-punish law enforcement. They enjoy revealing themselves in front of many intelligent creatures, especially when punishing evil and maintaining justice.
It just so happens that, as a non-human with half-dragon blood, Muria also enjoys engaging in these activities that Golden Dragons favor.
