Ostfrei is a moon of Genarius. The moon is very dark, with its unique orbit keeping it in the shadow of Genarius most of the time. Its thick atmosphere prevents most of the light that the moon do receive from reaching down to the surface.
There is not much of note on Ostfrei, so it is ignored by most of the residents of the Cularin system. Ships of the Thaereian Navy were sometimes seen around the moon.
