Sundriver

The Sundrives consitute an extragalactic civilization in the Orion's Arm universe.

Description
The Sundrivers owe their name to their large-scale actions, which is that of rearranging entire stars in a volume of about 3,000 light-years into a single, compact sphere.

Since the Sundrivers are located 60 million light-years away from the Milky Way, this means that all activity observed by astronomers in Orion's Arm actually occurred 60 million years ago. In other words, they already had star-moving technology at the dawn of the Cenozoic Era on Earth.

History
The Sundrivers were detected by the Argus space-telescope array. Since they Sundrivers are located so far away, the Terragens have yet to contact or reach this civilization. Even if contact were to be achieved, it would take at least 120 million years to send a message and get a reply, since there is no superluminal communication in Orion's Arm.
