Era: New Era

Lanth has a population between 10,000 and 10 million sophonts, lacking the industrial base to be completely self-supporting. This system serves as the capital for the subsector. It is a member of Regency of Deneb in the Lanth Subsector of Spinward Marches Sector. The system supports both a Regency Naval Base and a Scout Base with the additional starship traffic.

Description (Astrography & Planetology)

Lanth is a non-industrial world separated from the majority of its subsector by the Abyss, and is only accessible through Lunion Subsector or by jump-4. While this is not very important to naval or some scout vessels, its location has a significant impact on trade.
