The Two-sun planet is an Earth-like planet located in the goldilocks zone of a binary star system.
Overview
The planet houses indigenous flora and fauna, though it is unknown whether native intelligent life exists.
History
Before Apocalypse One, Eligius III had been sent to this planet. Eligius Corporation was looking for a planet to tap for oil, since Earth's reserves had been sucked dry. The Eligius III crew had their blood altered, i.e. given the Nightblood serum, to better withstand the two suns.
After Monty cracked the Eligius III files, he set Eligius IV to travel there from its orbit around Earth. It took the ship 75 years to reach it.
