I've just stuck up some very old notes of mine of an SF campaign setting I was thinking about around 10 years ago. Based around the idea of traversable wormholes. http://www.glendale.org.uk/onetime Released under GPL. No system associated with it. I'm probably going to tinker with it some more, though it looks like I may be actually running some Yags again sooner rather than later. I haven't finished clarifying how wormholes work (there's lots of relativity involved), and until I do, this may help: http://www.aleph.se/Trans/Tech/Space-Time/wormholes.html -- Be seeing you, --------------------------- Sam. http://www.glendale.org.uk/
