The Fringe

The Fringe (also called the Imperial Fringe, usually by parties outside the Empire) is a region of space bordered by the Imperial Picket and the encroachment of the Blacktrons.

The planets considered part of the Fringe include New Jerusalem, Oasis, Regis Major, and the Blacktron desert world. Also found nearby are the hidden asteroid base to which Spaceman of Futuron retreated after his battle in New Jerusalem, as well as the uncharted world on which he first crashed at the beginning of the Spruesworth Saga.

Sunbeam, Caspar, and Dorian are also called Fringe planets, despite their location on the far side of the Imperial Picket.

The realm of the M-Tron is in the opposite direction as Blacktron space from New Jerusalem and Oasis.
