Aetos Spyridon (1494 - unknown) was a Greek nobleman living during the Renaissance and, unbeknownst to most historians and philosophers, the Mentor of the Greek sect of the Assassins, a title which he held from 1517 - 1537. He was also an ancestor to Jason Cosmos but wasn't related to Camille Demonde. A member of the House of Spyridon, Aetos remained unware of his Assassin heritage until his parents were murdered in 1502, prompting him to flee and eventually begin the long road to becoming an Assassin in 1504.
