The Blessing



The Blessing was the name given to a second pole of the Earth, going from Buenos Aires to Shanghai. The Three Families used it to cause the miracle, by feeding it the blood of immortal Captain Jack Harkness. Being close to the Blessing caused many to feel uncomfortable, and seeing it was said to show people their true selves. In certain cases, this was known to drive some people, such as Zheng Yibao, to suicide.

The Three Families discovered the Blessing's presence by realising that the average lifespan of people living in Shanghai over the Blessing was the exact same as the global average human lifespan, and had been so throughout history. The Blessing is the focus of a morphic field matrix that encompasses all humankind, and the Families were able to alter it by introducing Jack's blood on both sides of the fissure. Jack theorised that the Blessing perceived this as an attack, which is why it was trying to keep everyone alive. As a mortal, Jack's blood was attracted to the Blessing. Introducing his mortal blood on both sides, via Jack himself and Rex Matheson, reversed the process. It was later sealed off by UNIT.

Despite being in charge of the Blessing, the Families were not entirely sure of its exact nature, such as whether or not it was a living organism. When pressed by Gwen, Jack speculated it might have something to do with Racnoss huon particles interacting with the Silurian hibernation field, but was forced to admit he had no idea.

The Three Families were unable to repeat the process because Holly Mokri had already destroyed the Key, the facility housing extra stores of Jack's immortal blood. (TW: Web of Lies)
