They were to be the guardians of peace and balance in Verathea.

The Sentinel Dragon and the Tempest Dragon were Althea's first two creations in the moments after the genesis of the world. They were to be the guardians of peace and balance in Verathea. They were noble creatures of enormous power that ensured many generations of peace and justice in the world. Indeed, so great was their will that they maintained their purpose even after the goddess was poisoned. Alas, when the Void Dragon came from Verathea's dark twin, the dragons of Althea faced an enemy unlike any they had ever seen. The Void Dragon was their counterpart, as powerful alone as the Sentinel and Tempest Dragons were together.

The battle between the dragons was titanic, shaking down mountains and razing forests. After much time though, the Sentinel Dragon and the Tempest Dragon were able to defeat Void Dragon at the cost of the Tempest Dragon's life. Yet even in defeat, the Void Dragon's evil could not be extinguished. The soul of the Void Dragon slid into the lifeless body of the Tempest Dragon, raising it as an undead monster dripping with corruption. Tears filled his eyes as the Sentinel Dragon battled the possessed body of his beloved brother.
