Polarian Prime


Polarian Prime is a planetary system orbiting a yellow G-class star.  The system lies in the Camelopardalis Constellation of the Polaris Region.  The binary system consists of two stars, the brighter g-class star and dimmer k-class star.

Polarian Prime is the center of the Polaris Region.  The primary planet is the population and economic center of the region.  The planet has a long and often violent history plagued by a string of wars.


Polarian Prime is a military powerhouse in the Inner Sphere.  The planet and it's people have embraced its military and conflict dominant history.  This history has included nuclear wars that have left parts of the planet uninhabitable.


Despte the numerous worldwide conflicts, Polarian Prime has still grown one of the larger populations in the Inner Sphere.  Polarian Prime has been a technology developer and innovator, often spreading its accomplishments throughout the Polaris Region as well as the Inner Sphere.
