Plot
In Alexandria of Egypt in 48 BC two people in black robes pay the thief Menis-Ra to destroy some papyrus scrolls kept in the city’s library. He succeeds, but a single amphora containing a scroll rolls through a hole into the sewage system. At present time Nina is having a nightmare about her upcoming marriage with Max. In her dream the church is suddenly on fire, Max disappears and she sees a man in black robes. She wakes up beside Max and shortly after, men in combat suits storm the apartment and arrest Max saying that he is accused for terrorist activity, while Nina later learns that there isn’t an official claim for that accusation nor his arrest. As Max is taken in custody he says something about their upcoming honeymoon in Australia and Nina, starting from this phrase, searches his apartment and picks up a trail that leads her to Max’s office in the Berlin museum. She finds that in the last months Max was interested in an excavation site in Potbelly Hill in southeastern Turkey, where he was called by Emre Dardogan. Apparently in the site they discovered a gigantic temple complex built over 11.000 ago (way before the Egyptian pyramids or Stonehenge) by people who vanished 2000 years later as if never existed. She also sees a photo of a monolith, taken in the site, and on the monolith she recognizes a carved depiction of the medallion which was worn by the black-robed people in the first game. She also finds a recorded message from Emre to Max, saying that he is hunted by the police in order to steal and silence his findings, and warning Max.
After finding these, she visits the excavation site in Turkey where she also learns that the temple was buried on purpose 1000 years after it was built, due to severe crop failures in the immediate vicinity of the temple. Nina finds Emre trapped inside and reaches him. He says that Max’s theory was that Potbelly Hill was contaminated with radiation thousands of years ago and in the temple Nina and Emre find the source of the radiation, which is an underground cistern with radioactive water. After Emre measures the radiation with his Geiger counter, two men in combat suits come in a car and pursue them, killing Emre, but they too are driven off the road by Nina, but also Emre’s body vanishes. Searching Emre’s laptop, the trail leads Nina to San Francisco.
While on the plane, she searches the laptop further and discovers that the amphora from Alexandria was found in a river in 1477 AD and that it was going to be sold by an Arab to a merchant in Florence. She then falls asleep and dreams of being in medieval Florence watching the events of the transaction. The Arab, after sending the amphora to the merchant, gets caught by guards who were paid by black-robed men. Nina frees him and follows him to the merchant, who apparently is Leonardo Da Vinci. Da Vinci hides the scroll because it contains a solution to a mathematical problem by Archimedes and he doesn’t want it to fall into the wrong hands. Nina finds the coded scroll and she discovers that Da Vinci hid Archimedes’ solution behind his painting “Madonna Benois”, just before the painting was sold to Lorenzo de Medici. She wakes up, before she can follow de Medici, by black-robed men who entered her dream and finds out that the painting is currently in an exhibition in the Palace of Fine Arts in San Francisco and she plans to meet the restorer Michael Anderson there (who also Max was going to meet). Meanwhile, all this time since she left Berlin, she is continuously spotted from a satellite.
