Maligor the Archfiend was the foremost of the Vorgar Lords whom entered Tarn during the Worldrending. He was unrivaled in strength among his kin, and when the Temple of Mal'Gazar was built, Maligor ruled there as a living god.
Maligor the Archfiend desired the worship of others above all else. In his home world of Al'Kazael, he had enslaved millions to serve him by building great innumerable monuments in his likeness. He continued this tradition in Tarn.
Humans had not yet come into the world, but the Fae were numerous. Maligor took many Fae as his consorts, and their monstrous offspring were the Ettins.
Maligor was slain by Ereus in single combat during the Battle of Mal'Gazar. Then, the remaining Vorgar Lords were bound in the Lightless Halls, in the Netherworld. The offspring of Maligor were not completely destroyed, and so they continue to roam in Faeheim.
