Regiariax, or Nightscale as she is sometimes called, is a Black Dragon, living in the Evenmoors after having been banished a band of heroes. It was seventeen years ago, when young Lord Jarmaath was a member of an adventuring band known as the Knights of the Vale, he and his companions encountered a very young Regiarix in the Marth Forest near Elsircross. Jarmaath landed a lucky blow that sent Regiarax fleeing for her life. The dragon returned several hours later to find that his treasure had been stolen by the adventurers, down to the last copper piece.
This did not sit well with Regiarax and slowly he has been accumulating a new horde along with new allies to exact revenge.
