Rubian

In the first episode Rubian is only a name: Lucienne tells Margaret that the Monarch of Rubian V has contacted her, because they found out that the moon they live on is made of pure lithium SOE1·01:12:45.

In the second episode the Red Hot comes out of faster-than-light travel at the gas giant Rubian, which Brennan describes as a luminescent, deep blood red gas giant whose storms are filled with quintillions of tons of diamond dust SOE2·01:15:41. He says more than a dozen moons circle it, among them Rubian V, a lithium moon about a third the size of Earth with an atmosphere and oceans SOE2·01:15:41. In orbit around Rubian V he shows the UFTP-owned Madrugada Station SOE2·01:15:41.
