The Age of Reason
According to legend, the Vaer were the ones who taught men how to use magic. They taught humankind how to bend the Essence to their will, as the Vaer were much more closely connected to the Essence, and the Pure One, the being of Pure Essence who they believed was the source of all magic, power, and life on the world.
The Vaer died mysteriously in the year 52 of the Empire, leaving behind very few survivors. Of those that survived, most were very young, and the rest either lost their powers, or lost their minds. The event seemed to have happened instantaneously, and has come to be known as the Genocide. Though many have attempted to study Genocide, no one has come up with a concrete answer as to what happened, though there are many theories that exist.
Many Vaer who were very young at the time of Genocide still live among the people of Drathl, most commonly in the Celeria Province. If anyone is interested in playing a Vaer, let me know, I will get you their racial stuff.
