However, the void ship had nothing to do with the Cybermen and had in fact been created by the Daleks (voiced by Nicholas Briggs), four of whom had used it to escape the Time War. Caught between warring Daleks and Cybermen, many Torchwood workers were either killed or "upgraded" to Cybermen (including Hartman herself—although she retained some semblance of her identity). In the wake of these events, referred to as the "Battle of Canary Wharf", the Institute feels it must "learn by heart" a lesson about its own arrogance. It was later revealed that the London branch of Torchwood, called Torchwood One, lost 796 members of staff and was ultimately ordered to close by Queen Elizabeth II. The threat is ended when the Doctor and Rose Tyler use Torchwood One's equipment to banish the Daleks and Cybermen into the Void between worlds and end the invasion.
