Cybertron

Cybertron was a planet that exists...somewhere in the vastness of space, or more likely, in an alternate universe...but not that universe...

Moons
Cybertron has several moons. At least three, possibly four of them are visible on some covers of various issues of Magic of Cybertron. The moons names are Hecate, Artemis, Artemis, and Cyberion. They also have the much more boring names of Moonbase I-IV.
