A wide region of the Delta Quadrant ruled by the Devore Imperium, where telepathy is outlawed and passing ships are repeatedly searched, crossed by Voyager in the episode Counterpoint.
Devore space is the territory of the Devore Imperium, a rigidly controlled state that treats all outsiders as suspect and all telepaths as criminals. Voyager has to cross it in the episode Counterpoint, set in 2375.
The ship is boarded again and again by inspection teams under Inspector Kashyk, who play classical music over the comm system while they search. Janeway hides her own telepaths, including Tuvok and Vorik, together with a group of Brenari refugees, by holding them in transporter suspension during each inspection.
The refugees hope to escape through a wandering wormhole. Kashyk then arrives alone asking for asylum and helps to find it, and he and Janeway grow close. His defection is a trick, but Janeway has planned for it and the Brenari get away in shuttles.
