Children of the Horned God

Before the forges of Klarglich were made, before the hounds of darkness issued forth from Austrag and long before the mogrl were crafted in the Pits of Woe, Unklar fashioned the ungern. When first he came through the portal, Unklar slew the high priest Nectanebo. After that, he fell upon the Emperor's Guard and the God-Emperor himself. All fell to the Horned God with an ease that made that beastly creature forever after hold great disdain for the folk of the All Father's fashioning. So immediately he gathered to him the substance of the Void and with the language of his Father, he crafted the ungern, the "black spawn." Some say that they were born of a union between the dark fey and wild evil men enslaved in Unklar's service. But this is not so; they are of the Val-Austlich, those creatures forged from the Language of Creation and the Val-Eahrakun, of which Unklar was one of the greatest. The Judgement of Corthain does not bind them and the ungern move freely about the planes as few other creatures can.

The Ungern served Unklar as soldiers and captains, and spread his evil throughout the lands. They were the battle lords that destroyed Kayomar, drove the elves of the Shelves of the Mist into ruin and plundered the dwarf halls. Their numbers were great and they led the armies in countless battles, ever in the service of their dark master. They filled the holds of Aufstrag with their evil and their numbers grew beyond scope.
