The Belis planetary system excists of three planets.
Belis Alta, Nova Belis and Belis Auris which all move around their single sun,
Aurora. The Belis cluster itself was was right at the edge of the Segmentum
Pacificus with Tanith being the closest planet.
The Sun Aurora had
been burning bright and warm for thousands of years. When the belis sector was
first discovered by the Imperial pioneer fleet of Admiral Avarell Prichard it
was Aurora that had guided the fleet in like a beacon of light and hope in the
vast darkness of empty space.
