[b]One thing to remember is that Halo and Star Wars exist in entirely different Galaxies, so there would have to be quite a bit of travel[/b] It would take a lot of work to get all 12 of the original Rings to a whole other Galaxy. Also that much slip space travel would screw the crap out of the fabric of slip space, resulting in some nasty accidents. Enough to put a major dent in a fleet. And I don't think the Halos would have an effect on the Force itself. It have quite an impact though. Isn't the Force tied up with all living things? Well if we go with that then the Halos could actually cripple the Force, as they can be used for more than just sentient life. Change some settings, and Halo can wipe out all life in a smaller area.
