Japetus

Japetus was the second moon of Saturn. Circa 3985, there were three man-made colonies on the moon.

An account claimed one of the colonies was Kaldor City and that it existed on the edge of a vast sandy desert, with the Founding Families (the initial terraformers) governing Japetus. (PROSE: Legacy) However, according to all other sources, the City and the Families were in fact on the planet Kaldor. (AUDIO: Occam's Razor, COMIC: Crisis on Kaldor)

Japetus was one of the planets which adopted the New Astrology created by Kasterborous. (PROSE: Short Trips: Zodiac)

In the 30th century, Japetus was part of the Earth Empire. (PROSE: So Vile a Sin) Centuries later, minerals were being sent to Io for distribution throughout the Galactic Federation.

In 3985, the mercenaries Lambert, Sadler, Cooper and Townsend left Japetus in stolen Federation shuttles. (PROSE: Legacy)

Behind the scenes

 * PROSE: Legacy implies that TV: The Robots of Death was set on Japetus, but all other sources indicate that it wass located on the planet Kaldor. As pointed out in REF: AHistory, Kaldor City is located far from Earth space and has no interstellar trade. Though, as with cities in the real world, it is always possible there are two Kaldor Cities.
