A man, from another world. Argent was his home. But his world was betrayed by a priest called Deag Garv. Deag was not a priest of God, but that of hell. He destroyed and took over Argent D Nur from its rulers. Called it Argent his home, a hell filled with demons beasts monsters all ઉ holiness the Mastermind.

Doos wears an armor called Praetor suit which has interfaces for taking from Sam ActiveX that Sam created. Thus he is able to take or be given from Sam. But he must also be able to give to Sam. This he achieves through the wraiths and the crucible. Deag Garv designed Doos’ suit, and turned out to be compatible with Sam’s ActiveX. It originally built for pure Argent energy that flowed in all hell.
