Ide is an ancient substance that was used by the Danuar as the main energy source for their weapons, devices and other creations, such as Hyperion. It was first introduced in 4.0 and has since been highly sought after by the Elyos, Asmodians and in particular the Balaur. Ide harnesses great power but comes with equally great risks: it is shown to be highly unstable and has disastrous effects on both animate and inanimate objects if not handled properly or if direct contact is made with it.
