In July 2005 as London celebrated winning the rights to host the 2012 Olympic Games, a series of deadly explosions ripped through the city.

On the same day in Scotland the G12 Summit of world leaders was interrupted as protesters stole the Stone Of Scone from a temporary display in the lobby of the Gleneagles Hotel.

So continued a chain of events set in motion over 700 years before.

Events, which if allowed to follow their course would lead to Armageddon – The End of Days –

The annihilation of 4 billion people.

One last holy war could destroy the world. Unless the riddle is solved of a mysterious green stone kept hidden in Buckingham Palace for the last 150 years.
