The Four Dragons

The Four Dragons
It is believed long ago during the first age, dragons and dragon kin ruled the world. Tiamat, a creature of cosmic power came to be within the world, a dragon with 10 heads threatened to annihilate all of the world in what is called a Ragnarok.

There were five remaining lord dragons; dragons born before time it's self: Xoimir of the Bronze Kin, Quilryn of the Red Kin , Korkirth of the Gold Kin , Vedlyr of the Green Kin and Sipheth of the Silver Kin. These lord dragons took up arms against Tiamat setting aside their hatred for each other in an attempt to defeat it and protect the world from Ragnarok. The alliance unfortunately was in vain as Tiamat proved to be too strong, destroying the dragon's homelands near The Argent. As a last attempt, Sipheth, the Silver Kin, and the White Kin all sacrificed themselves to banish Tiamat to another plane.

The remaining four of the Lord Dragons who stood up to Tiamat, took the remaining dragon kin and brought them across The Argent to what is now called the The Badlands and made their home in the mountains and volcanoes there. Eventually the four remaining lord dragons disappeared without a trace. Many assume they finally decided to pass on, and help their brethren in the afterlife to fight Tiamat

Now, eras after the events of the first age, the dragonborn and other dragon kin adamantly perform rituals to keep Tiamat at bay, though now a days the other races doubt that these rituals even do anything or if any of the stories of Tiamat and the lord dragons are true.

Beliefs
Dragonborn and other dragon kin believe they sacrifice the souls of their deceased to the plane that holds Tiamat, to fight along side the white and silver dragons in their struggle to keep Tiamat held. The dragon kin believe that they must be worthy in their life, being strong warriors, being master craftsmen, being the best they can be will lead them to having the true strength to fight Tiamat in the afterlife.

The rituals, such as the trial of the red dragonborn, where they take hatchlings to the volcanoes of the badlands and leave them there for a fortnight are just one of the many examples of the tenacity and determination of the dragon kin to be as strong as they can be.

Deities
The dragon kin and other believers hold the four surviving lord dragons as the representation of what a dragon should be, and idolize Sipheth for her and her kin's sacrifices.
