The emergence of dragons in the Disputed Lands coincided with the events of The Rift. It has been theorized that the intensity of the volcanic activity casued the dragons to awaken from their slumber.
The Drathian dragons are of a different species and predate the dragons of the disputed lands by centuries. The dragons of Dirath have a slower reproductive cycle than their relatives. This, combined with their constant struggle with the Drathians has diminished their number in the past hundred years. They remain, however, a constant threat for the Drathians and anyone traveling on the opens plains of Dirath.
