Age of Heroes
The Donaarian Pact
The Donaarian Pact was an alliance of all of the tribes of the Dragonborn under the banner of Donaar, who was believed to be the avatar of Bahamut himself. The Pact was formed in order to defeat the Kragan Empire which threatened to extend its reach into the Eastlands, and beyond.
Donaar himself, though a wise and respected leader, cared little for governance. The Pact was less of a state and more of a military alliance of already existing tribes who put aside their differences to unite against a common enemy. After the Three Crowned Alliance successfully crushed the Kragan Empire, Donaar continued to rule the Eastlands, and managed to keep the Dragonborn united from 7216-7302, at which point it was revealed that Donaar was long dead, and his son and grandson had been ruling in his stead.
