Temporal disruptor

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
While not named in any source this Wiki deems valid, 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.
