Unlike most other dragons, Virtue Dragons are born with an innate sense of right and wrong. They value morals above all else and choose to live in seclusion, away from other dragons. They will only cohabitate with dragons and dragon keepers who they believe to be of the highest moral fiber.
Virtue Dragons are very selective with whom they choose to associate. Often, they will covertly observe a new possible roost for days, seeing what good deeds its current inhabitants perform throughout the day.
While Virtue Dragons are very virtuous, they are also a bit on the arrogant side. When one chooses a new home, it does so in a very prominent, almost ceremonial fashion. As such, having a Virtue Dragon choose to live on your island is considered to be a great honor.
Epic Virtue Dragons do not need to be as vigilant in promoting moral behavior since the mere presence of an Epic Virtue Dragon actually causes moral behavior! Top dragon scientists believe this is due to an aroma that these dragons emit, which causes those exposed to it to become more reminiscent of a time in their lives when they were more virtuous.
