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 attempts to penetrate the Doctor's TARDIS but fails. They are destroyed at the end of the war when the Tenth Doctor blows up a disused refueling station on the planet Hurala, taking Dalek X's Exterminator with it. (PROSE: Prisoner of the Daleks)
