"Details are sketchy in the galactic databases on the Antipode system. It was a member of the Old Republic, settled by a mix of sentient races. Due to a nearby supernova approximately 1,000 years ago, the hyperlanes connecting Antipode to the rest of the galaxy shifted, causing it to be unreachable. During last days of the Clone Wars, CIS scouts detected a large hyperlane shift and rediscovered Antipode. The last official records indicate that at the close of the Clone Wars, the Antipode system was absorbed into the Galactic Empire as an Imperial Species Preservation Zone with extremely limited civilian access."
This should be interesting, as it will be the core setting of an Edge of the Empire campaign. :)
