Imagine a universe where a set of Stargates connect distant worlds. Many of these worlds have a low level of technology, and often fear and distrust those who come through the Stargates. The secret of making the Stargates, and who and why they made them, is only distantly known. Now imagine an expedition of individuals going through the various Stargates, seeing the various worlds that they connect. Meeting the human and not quite so human races to be found on these worlds. So far, you should be thinking of Stargate, the movie and its sequel series Stargate SG-1, Stargate: Atlantis and Stargate: Universe. Now imagine that it was determined that the Gates had destroyed a galactic civilization, and could still change and wipe out worlds and polities with a careless bit of travel. And so this expedition’s mission isn’t just to explore the Stargate network — but to destroy it, one gate at a time. The science fantasy Morgaine novels, by C.J. Cherryh, explore the quest of the last member of an expedition to do just that.
