Temporal Research Team

The Temporal Research Team was a group of Dalek scientists and created a Large Chronon Collider to get the Arkheon Threshold during the Second Dalek War. They attempted to penetrate the Doctor's TARDIS but failed. They were destroyed at the end of the war when the Tenth Doctor blew up a disused refueling station on the planet Hurala, taking Dalek X's Exterminator with it. (PROSE: Prisoner of the Daleks)
