Abaddon

Abaddon is the name of an outcast God cast down by the Gods of Tyria long ago. In Nightfall, Spearmarshal Kormir suspects that Varesh Ossa and General Kahyet, her respected mentor and loyal officer, are worshippers of this deity and are trying to bring about its return. Abaddon has a location named after itself - Abaddon's Mouth, which symbolizes a hellish gateway to the Underworld.
