Naraj is an ocean moon, with a very thick ice sheet covering the planet. The moon’s close proximity to a giant like Yridia VII warms the core through gravitational tidal forces, allowing a liquid ocean beneath the ice sheet. The atmosphere is tenuous, but thick enough to allow humanoids to wander about with the aid of masks. Though the moon is well outside of the radiation belts of Yridia VII, inhabitants use an energy shield to block most of the harmful solar radiation that penetrates the thin atmosphere. Strong winds with blowing ice crystals plague the entire surface constantly. Though the atmosphere is thin, dust and ice storms still occur, mostly obliterating existing craters.
