We had brought suitable worlds from nearby systems, increasing our agricultural worlds to four, and setting them in a Kemplerer Rosette. It was necessary to move them all simultaneously when the sun began to expand, and to supply them with sources of ultraviolet to compensate for the reddened radiation. You will understand that when the time came to abandon the galaxy, two hundred years ago, we were well prepared. The five worlds are heading towards the Lesser Magellanic Cloud some 200,000 light years away. A few humans have been allowed to settle on one of the farming worlds.
Conservatives use the humans to investigate dangerous regions in the path of the migration.
Hyperwave Puppeteers have the ability to track ships in hyperspace and communicate through hyperpulse in a gravity well, two feats which baffle Known space scientists. It is suspected the Puppeteers bought these two items of technology from the Outsiders to assist in the second exploration of the Ringworld. In addition, the Puppeteers also have more advanced thrusting systems which can sustain higher accelerations than those units carried by Known Space ships. To the Puppeteers, the Quantum II Hyperdrive shunt was a white elephant. It would move a ship a light year in one and a quarter minutes, where conventional hyperdrives would cross that distance in three days.
