Empire of Nerath

The Empire of Nerath was the last great empire, it came to power after the fall of the tiefling Empire of Bael Turath and the dragonborn Empire of Arkhosia. The Empire of Nerath enforced acceptance of all 'civilized' races so that inter-racial struggles, the likes of which resulted in the great war and ensuing destruction of Bael Turath and Arkhosia would not destroy it too. Nerath was a human-dominated empire.
Until recently it was thought that the Empire collapsed in 802 GD, but Mermin of Dofngarth discovered evidence that the empire actually fell in 752 GD after a 9 years of rapid deterioration.
