When Leonardo da Vinci painted his Last Supper he did not know that on the table in front of Jesus Christ was a shallow wooden tray, not quite square in shape and measuring about the span of a hand across. Laid out in the tray in a special pattern were thirteen pieces of pot, varying in both colour and shape, and each one with a Greek letter engraved into it. During the proceedings Jesus gave out the pieces to his disciples, keeping one for himself. Over the next half century the pieces travelled far and wide with their owners, then became lost to the world.

A chance finding of a Dead Sea Scroll almost two thousand years later revealed an account of the Last Supper. It also revealed that if mankind did not 'mend its ways' God would destroy the Earth and all that lived upon it. But he did give mankind a get-out.
All thirteen pieces of pot had first to be located then re-assembled in their origin positions within a wooden square by the leaders of the thirteen most powerful nations in the World to show their commitment to making the world a better place.

The task of locating the pieces fell to a professor of archaeology at an English University. Once done 'Christ's Holy Square', as he called it, was re-assembled at the UN. But that wasn't the end of the story for mankind did not keep its promise. God was about to wreak his revenge when he discovered a threat from far beyond the Sun's boundaries.
