The Void dimension was a peculiar one. Not like any other dimension that we have visited up to this point. There was never anything in it, to begin with. It is said that when The One created the universe (or universes), a vacuum came into existence as a result of the liberation of the holy power of cosmic proportions, thus birthing into existence the Void dimension, where nothing lies, and nothing ever leaves. Things that are lost are believed to turn up in this place. There wasn't, however, a known way to enter this dimension, let alone to get out of it.
