Okay, so this is the ancient homeworld of the Sith, both the species and the Force-based religion.  It's a semi-arid desert world, for the most part, though not as severe as Tatooine's conditions.  It is famous for its red sands and mountains, along with the monuments, tombs, and academies of the ancient Sith that dot its landscape.  It is not a friendly place to be for a Jedi, as it resonates incredibly strongly with the Dark Side.  However, it can be equally inhospitable to a Sith, as not everyone of the dead that reside here remain silent, if you believe the stories.  As of late, the planet does boast an imperial presence, though mainly its academic and archaeological rather than military, as the Emperor seeks some of the secrets of the ancient Sith that have been lost to time.  The deserts and valleys are very stubborn, however, when it comes to revealing their secrets, some of which should probably be left buried.
