Mongo is a rich and agricultural production world with a shirt-sleeve atmosphere and a balance of available surface water. The system supports a population in the millions of sophonts, lacking the industrial base to be completely self-supporting. It is a member of Third Imperium in the Jewell Subsector of Spinward Marches Sector and in the Domain of Deneb. Mongo, as a member world of the Third Imperium, holds the estate of an Imperial knight (the Imperial representative to the world) and the fiefdoms of a baron and a minor duke. All three are members of the Imperial Landed Nobility who oversee affairs regarding the world at an Interstellar and Imperial level. The system supports both an Imperial Naval Base and a Scout Base with the additional starship traffic.

Description (Astrography & Planetology)
