So the other day I was researching Charles Darwin and evolution n such. I came across a Persian Scholar by the name of Nasir al-Din Al-Tusi who put forward the basic theory of evolution 600 years before Darwin.
As the armies of Genghis Khan swept his homeland, he was employed by the historical Assassins and made his most important contributions in science during this time when he was moving from one stronghold to another. One of those strongholds was Alamut, where Altair got the memory seals.
He was captured after the invasion of the Alamut castle by the Mongol forces.
Ubisfot has confirmed that there will be references to Edward Kenway in Syndicate, and guess who visited Alamut.
