Earthstone is a rare stone.
Nearly the "sum" of the incorrect equation given by Wraith's people, Earthstone is a combination of some of the rarest, purest stones on the planet Earth, including Jadeite and Serendibite. Mixing and remixing these stones, Earthstone is created, a technology that is far beyond any available to mankind in the 20th or 21st centuries, and seeming physically similar to Kryptonian Sunstone.
Wary of its potential, General William Rudolph sabotaged the equation used to make it, leaving him and his grandson, Jonathan, the only ones with the knowledge of how to make this creation and mine the necessary materials.
In the year 2013, this knowledge was used by Jonathan's terrorist organization, Ascension, to attempt to erase the work that Wraith's people had done to aid mankind's progression, allowing them to develop on their own terms.
