With an underground bunker built by expending the immense wealth of the Financial City, specifically designed to counteract extraordinary disasters.

London time, 4:34 AM.
There are 5 minutes left until the disaster strikes.
In the northwest of London, Blighley Manor, home to a Turing Department with secrecy levels comparable to Buckingham Palace, was equally in chaos.
This was the most important code-breaking center in the UK during World War II, where mathematician Alan Turing led the development of the "Turing Bomb" code-breaking device, greatly enhancing decryption efficiency.
Although Turing is no longer here, within the manor stands a massive, old electromechanical device.
It's called the "Imitation Game," epic quality, capable of glimpsing into the past and predicting the future to a certain extent, even more accurately than the prophecies of the Navigator Guild.
