Tantalus field

The tantalus field is a device that allows users to monitor, transport to or elimiate a person from a location within it's range at the touch of a button. It is known to have esxisted in both to primary universe and the mirror universe. (, : "Trial By Fire")

The tantalus field was first encountered by Captain James T. Kirk in 2267, aboard the ISS Enterprise (NCC-1701) in the mirror Universe, where his counterpart owed his success against a number of enemies to the tantalus field, and the unknown alien scientist whose lab he plundered for it. The field was apparently a secret from everyone except Marlena Moreau, and to others it seemed that Kirk's enemies had a tendency to "simply disappear." The field was used by Moreau to save the "original" Kirk when he was trapped in the mirror universe. 

In 2274, the tantalus field was discovered for the first time in the primary universe by Lieutenant Sara Parker in a Preserver temple on the surface of Tyra III. Parker used the device to eliminate a Jem'Hadar patrol that was threatening an group of Archiologists before also using it to transport them aboard the USS Argus (NCC-75124) in orbit and transport herself to rescue another group of captured survivors from the Seventh fleet. A science and engineering team deployed from the Argus to the planets surface to study the device, when its power source started to fluxuate. The field was used on final time to evacuate the team before the power source went critical and tantalus field was destroyed along with the rest of the temple. (: "Trial By Fire")


 * In a story planned for an unrealized William Shatner guest appearance on Star Trek: Enterprise, it would have been revealed that the Tantalus field did not kill its victims, but transported them to a different time. "Trial By Fire" expanded on this by including a gateway as part of the device that could transport a person to a different place instead.
