Eligius Corporation

The Eligius Corporation is a mining company that carried out interstellar missions to mine asteroids and to search for habitable planets. Eligius IV is one of the ships owned by the company which transported prisoners to the Asteroid Mining Penal Colony.

History
The company was started before the Nuclear Apocalypse and began deploying national prisoners in order to mine Hythylodium from the asteroid Proxima Six.

Eligius I was an unmanned explorer ship which was sent to the asteroid Proxima Six and found Hythylodium gold mine.

Eligius II was the first manned mission to mine Hythylodium, but it failed because it didn't have enough manpower, which was the reason why they switched to prison labor for Eligius IV.

Information about Eligius III is encrypted but it is known that Nightblood was used on it.

Throughout the Series
In Echoes, an article titled "Contact Lost With Asteroid Mining Penal Colony" from the West Coast Herald can be seen on one of Raven's monitors as she explains 2048 nuclear reactor technology to Jasper and Monty. This is the first mention of humans living in space farther out than Earth orbit. It was implied that the Eligius Corporation was involved with the penal colony in space as well as mining.
