A technologically advanced race has vanished, but their teleportation system remains, strewn over scores of planets. A few people still know how to use the gates. Some are despots using them to reach and conquer new worlds, and these campaigns are killing cultures and in some cases whole planets.
Morgaine is on a quest to find and destroy the remaining gates so that the vulnerable cultures can evolve to the spacefaring level without interference. But the Genghis Khan wanna-bes want her dead.
