History
Before Apocalypse One, Eligius III had been sent to this planet. The Eligius Corporation was looking for a planet to tap for oil, since Earth's oil reserves had ran dry. The Eligius III crew had their blood altered, i.e. given the Nightblood serum, to better withstand the two suns. According to Eligius IV's records, they never reported back or they did and it was after Apocalypse One. Either way their status is as of yet unknown.

Later, Monty Green, after many years of research, cracked the Eligius III files after 30 years on Eligius IV, he set it to travel there from its orbit around Earth. It took the ship 75 years to reach the planet and when it did, Monty and Harper McIntyre’s son Jordan Green woke up from cryosleep as his father set to. He follow his father's instructions and awoke Clarke Griffin and Bellamy Blake. He went on to show his parents' friends many videos and a new planet, where they can call home.
