He is a demi-god, more precisely he arose from the desire to invent and innovate technology, he feeds on the concept of technological creation, his plan is to become the fifth Chaos God and get into the Great Game of the other 4, not being a God complete can enter in the reality but with only a fraction of its true power. He has the ability to understand any technology regardless of its origin, he can interact with AIs and sense the use of technology, the Mechanicus thinks that Vashtorr was the culprit in the dark age of technology bringing the rebellion of the AIs, and the Dark Mechanicum adore him but they do not consider him the Omnissiah.
