A few centuries before 2059, an alien race opened the Time Fracture with a temporal disruptor until all of the universe collapsed. The TARDIS saw this and decided to use it in 2059 to help the Tenth Doctor become a better person. (PROSE: What the TARDIS thoguht of "Time Lord Victorious") In the 2020s, (WC: 14681 UNIT Field Log, etc.) UNIT issued a Field Log to the participants of Operation Time Fracture that they knew Zoria was searching for components to a device that will save the world. (PROSE: Zoria) UNIT Sergeant Robert Dudley, who had stranded in Elizabethan England after travelling through the Time Fracture, (WC: This is Sergeant Robert Dudley., Dudley here.) noticed Zoria (PROSE: Zoria) had "collecting various parts" though he wasn't sure what they were doing or building. (WC: Is anyone receiving these transmissions?)
Behind the scenes[]
The device originated from the immersive experience Time Fracture, where it was revealed that the device was a Time Disruptor. Zoria had been building it to reset the universe so the Time Lords could preside over a new one.
