The Age of Muldorn and the rising of Ullanis.

When Muldorn, the immortal dunruvali, god of cold and undeath, was called down to earth by the Ullanis Empire, he broke the Pact and forsook his godly position in Adrenergard.  He came down and took on a fleshly mantle, and assumed the throne of Ullanis.  He made the small empire great; with him at the head of an army, they were unstoppable.  Until, after taking part of Felldar, he lead the Ullani army to the Belannor Empire, where, at the Battle of Edölas, Alderath the Ageless used the Shield of Boleras to defeat the fallen god and his army.  After that, the Ullani army retreated back to Ullanis, and stayed there for many years.  But slowly at first, Ullanis's borders expanded again, it became the biggest empire in the world.  The elves retreated back into their forests, the dwarves sealed their tunnels, gnomes surrounded their homes with illusions and locked their doors.  Yargal, orcs, and goblins roamed in the now empty lands, halflings fled from their rural, riverside villages, and went to the big, fortified human cities.  The undead of the Gray Plateau, or Krod, praised Muldorn, and joined under the Ullanis banner.  The human nations were left to ward of the Ullani expansion.  It was dark times, men had been forsaken by the elves and dwarves, and Ullanis was an unstoppable juggernaut, until an Oréalionder prince and his friends rose up and worked against Muldorn.
