The Deep Core Flux route was the name given to a hyperspace route that led from Coruscant to one of the few habitable regions of the Deep Core. The route was usually blocked by the mass shadow of a relatively large black hole (though not as large as the one at the very center of the Galaxy), which wobbled in and out of the way by the gravitational pull of a star cluster. The route is shrouded by vast nebulae, and is therefore undetected from navigational computers. Because of a curious gravitational setup, the black hole allows passage six out of thirty hours of the cycle. Because it is closed most of the time, it further evaded discovery by explorers and scientists.
