Okay, if you haven't played Da Vinci Disappearance, you may not want to read on, but really there aren't much spoilers i believe.
When you finish the game, you get coordinates 43 39 19N, 75 27 42W and a trophy called "GPS".
I went to google earth and typed it in, and it brings you to a crater of some sort, it's in Turin, NY.
Then some people mentioned the Shroud of Turin, and how it was a piece of eden, so I decided to look into it.
And I found my old book about unsolved mysteries and stuff - to find out more about it. What I found is rather interesting.
So I'll skip what most of you know, that it is supposedly a shroud that was placed on Jesus on his burial...after all, you can read it in wikipedia, I'll skip to the interesting part.
Now, recent tests proved that the shroud was made somewhere around 1200 to 1300.
According to Christopher Knight and Robert Lomas, they think that the face on the shroud is of Jacques de Molay - Grand Templar Leader!
According to Knight and Lomas, Templars had other goals when they invaded the Solomon Temple, Templars were actually looking for some old documents or pergaments. Part of pergament found was taken by a Templar to France, on it there were masonic insignias five centuries before masons formed! And that those documents were actually the great treasure Templars found.
On the fall of Acre 1291 templars lost the fight and french stole the treasure, or so they tried.
Just before Templars lost everything they sailed from France and vanished from history. (After Acre, Templars returned to France, but the king wanted to rob them)
At least one boat escaped to Scotland (One of the Temples was in Scotland, right?)and there William St. Clair build the chapel Roselin which was full with evidence that William was Templar. In the chapel, on some decorations there were images of corn and other plants which were only in America at the time, so it's hard to disagree that some of the boats escaped to America, half century before it was "discovered". But would Templars go on such dangerous trip not knowing what awaits? According to Knight and Lomas, one of the documents Templars found in Solomon Temple was a map New World.
Lomas and Knight found 10cm long picture hidden at the top of the stairs in Chapel in Scotland.
On it there is a headless person holding a shroud with a face on it.
Evidence suggest that it is indeed the shroud of Turin.
They also think that the face is the Great Templar Master, not Jesus.
Templar Master was tortured and crucified, after he under agonizing pain admitted of what they were accusing him of, then they stripped him down and rolled him into a shroud, he was sweaty and bloody which probably left the markings.
4 Centuries later, during French Revolution when Luis XVI ended on guillotine someone from the crowd yelled "Jacques de Molay is avenged!"
I placed a lot of effort into translating and finding all this, so please understand if there are any minor or major mistakes in translating.
I know it's not a lot, but it all points to next Assassin Creed being during French Revolution.
