Ordite, Conqueror of Worlds, is an extra-planar entity that had infected Aak with its dark essence.
Ordite revealed itself to the party while they were attempting to activate the Gate to the Sil with the staff called Countersign. It revealed a grand plan to take over the world by summoning three great armies through massive magical gates within Emathan. It also revealed that there would be no room for dragons within Ordite’s new world, thus the infection of Aak.
The party managed to barely defeat some of Ordite’s minions before entering the Sil and freeing Aak of Ordite’s corrupting infection.
