Toba Construct

A facility built by Drivers before the dawn of sentient life on Earth. The primary function of the facility was to act as a mass battery charger using mantle heat or wave generation. When Eve entered it she caused the facility to become overloaded and that caused a massive explosion and EMP that wiped out much of the technology on the world including several other Driver facilities on Earth. Duncan was able to shut down a bunch of them in time before they were affected by the EMP but not all of them were saved. He's still pretty mad about it.
