Piece of Eden

This is a story of Desmond Miles; someone who doesn't have any ambition in life but one day he got kidnapped and he encountered Templars (the long time rival of the Assassins. They seek control of the world at any cost even if it would mean to bring violence to the world)
and dragged him into the Animus so that the Templars will wield the powers of the Apple of Eden (the most powerful device known to man since the first civilization once hit by the lights coming out from it, the one who is hit by the light will die because the victim's brain will burst) to take control of the world. Now it is up to Desmond to figure out what to do to stop the Templar's plot.
