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 and the fiefdoms of a baron and a minor duke. All three are members of the Imperial Nobility charged with overseeing the world. The system supports both an Imperial Naval Base and a Scout Base with the additional starship traffic.

Astrography & Planetology[edit]

Mongo is a boom world with a quickly growing population due to huge amounts of metal deposits recently found close to the planet’s surface.

It is a part of the Jewell Cluster.
