The Dragonfall War was a conflict between the draconic followers of Bahamut and Tiamat. In some respects the conflict never ended. It began in the Time of Dragons, a period that lasted about six millennia from c. -30000 DR. It began when followers of Xymor (Bahamut) slew Nagamat, a wyrm-general of Tiamat. Tiamat unleashed all sorts of dragonlike beings during the war, breeding warped creatures from her eggs. These aberrant entities became known as the Spawn of Tiamat. To counter them, Bahamut created his own agents, the dragonborn of Bahamut.
