In the Creation War (1486 DE - 8777 DE), Sathumort was a Covenant officer. Of the Durkoth people, he went down the dark path, carrying out brutal campaigns against the Covenant's primordial enemies. When he died, his soul energy went to the world of Azu'tzor where it was reforged, with Sathumort reborn a Demon.
In the Demon Spawn War (89 GE - 269 GE), using an ancient weapon called Webreaver, Sathumort re-opened the Henmona Rift. Using this bridge between worlds, his forces left the world of Nasudex for the Cilarrion region of the world of Kriav. In the Year 92 GE, Sathumort's forces began their assault on lands and peoples under the watch of the Covenant general Corellon.
On 2 War March 135 GE, Sathumort opened another front. Again using rift-making sword, he cut a whole in the Web of Magic, creating the Sathumort Pocket. Several weeks later, the Maeraddyth Brigade traveled to Sathumort's home on Nasudex, slaying him while nearly all of his forces were laying siege to Liamenor.
