YEAR LENGTH: 200 standard days CLUSTER SIZE: `C' (700 mile diameter) NUMBER OF ASTERIODS: 2000 + DISTANCE FROM PRIMARY: 60 million miles
Like the Beta Cluster, this is a large collection of very small asteriods (size `A') in a smallish area; all part of a thinnish `shell' about a central size `B' firebody. All of the asteriods are 150 - 200 miles from the central firebody. Unlike the Beta Cluster, these asteriods all share a common air envelope.
The Zeta Cluster is unusual in that it was occupied when the Invaders first arrived. Prior to the Invaders arrival, teams of Grav's and Rockhoppers had staked claims on many of these asteriods: the Rockhoppers hunted the wildspace creatures that lived amongst these rocks and traded their catches with the Grav for manufactured items.
These days both races answer to the Invaders, who assumed control via a bloody coup some hundred fifty years ago. These days, the Grav `Elite' answer directly to various Invader flunkies, a situation they accept without comment.
