Deus
The physical aspect of Deus is part of the Yaweh (Yahweh) interplanetary invasion system, along with the Zohar. Created by an ancient civilization (20xx A.D. , when the Zohar was discovered on Earth) it was coupled with the Zohar to become a tool of unprecedented destruction. As is the case with AIs that have too much power, its ambition grew out of control and it was disassembled and placed within the Eldridge for removal. It took over the ship, however, and crash landed on the planet where Xenogears takes place, sustaining heavy damage. To repair this damage, it activated a repair system known as Kadamony. This repair system created a race of people which would one day revive it. It is the objective of the Gazel Ministry and Emperor Cain to restore Deus by changing all humans into Wels, which the god-machine would then absorb. The name Deus comes from the Latin word for "god", as in "Deus ex Machina" ("God From Machine).
