A device that lets a telepathic operator control a distant vessel by thought, used by the Romulans to fly their drone ships and copied by Enterprise in The Aenar.
A telepresence unit links a pilot's mind to a remote ship, so that the vessel can be flown from far away as though the operator were aboard. In the 22nd century the Romulans build one to control their holographically disguised drone ships, which attack shipping in order to set neighbouring powers against one another.
The system needs a strong telepath, and in the Enterprise episodes Babel One, United and The Aenar the Romulans use Gareb, an abducted member of the Aenar, a blind telepathic people of Andoria.
Archer's crew construct a version of their own aboard Enterprise. T'Pol tests it at some risk, and then Gareb's sister Jhamel uses it to reach his mind. Learning how he has been deceived, Gareb turns the drones on each other and is killed, ending the Romulan scheme.
