Dead Space (Ringo)

In the Known Universe, there is a phenomenon known as "Dead Space" where basically what looks like innocuous space is for some reason able to shut down all a ship's systems and keep them off. Ships that fly into dead zones will just shut down, life support will turn off, and the ship will float off into the void or smash into whatever objects sit within the dead zone. A popular story about such places is about when a Medrod carrier that had grabbed an entire planet flew into the dead zone near Aquad once, and the whole planet and the carrier's crew died when the ship shut down and floated away from that system's sun. The borders of dead spaces shift around a bit like waving water, but the zones themselves haven't moved in recorded history, though some have disappeared. A well-known dead space sits between Mongor and Dorgia, which has allowed Dorgia to exist close to the ruthless empire in relative peace.
