Selene

Location: System 4

Selene is the major moon orbiting Hillys, an inhabited planet in System 4. Its surface consists mainly of impact craters, rocks and fluids. Its surface gravity appears to be similar to that of Hillys, and it is the only other known celestial body in the system where oxygen gas occurs, though no nitrogen or hydrogen gases are found there.

Structures[]

The only known structures on Selene are a monolithic base of the invading DomZ, topped by a long-range broadcast station belonging to the Alpha Sections. The DomZ base is the lair of their ascendant High Priest, surrounding the Great Crypt where their Hillyan captives meet their end, drained of their life force.

The lunar transmitter station is where the Alpha Sections broadcast their propaganda to Hillys.

Beyond Good & Evil[]

Selene can only be reached by the use of a ship that is geared with a stellar-motor. Jade is able to acquire one from Mammago Garage, though it is not entirely 'new'. The final stage of Jade's exposure of the DomZ/Alpha Section trafficking conspiracy takes her to their lair on Selene. After hijacking their own transmitter to expose their crimes, Jade is dragged into a dogfight through the moon's canyons by General Kehck's ship. Upon the exposure of the Alpha Section, a strike force of Hillyan fighters also travels to Selene to engage the Alpha fleet.

Trivia[]

Oxygen apparently occurs on Selene, this is evident not only by the fact that Jade and her companions can breathe when outside of the Beluga (even when the shield is offline) but also because sound can be heard; sound travels through atoms (oxygen-atoms), which will vibrate and thus create sound.
Beyond the parasitic DomZ, no resident species are confirmed on Selene, although the moon does appear to contain water.
In Greek mythology, Selene is the goddess/personification of the Moon, as well as being the source for the contemporary Greek name for earth's Moon.
