Dragon Nations

The Dragon Nations consisted of dragons of all colors that united to fight Phyrexians during the Phyrexian Invasion. They were ruled by the dragon lords of each color, having Darigaaz as the red one. The dragon lords were sacrificed to awake Treva and other Primeval Dragons. Dragon Nations were under the control of the Primevals. Later, they were freed.
