Because Altair and his descendants moved around a lot to tackle different Templar threats across the planet (he took his sons to fight Genghis Kahn at one point).ReservoirAngel said:There's just a minor thing I've never seen ANYONE, despite whatever criticisms they throw around, mention at all about the Assassin's Creed series, and it's this:
How is a modern-day American man decended from an Italian nobleman, who is himself decended from a Middle Eastern bloke?
The Italian-to-American thing I can understand, but I'm not currently aware off any historical link between Italians and Middle Easterns that would allow a Middle Eastern bloke to have pure-blood Italian ancestors a few generations later.
There probably is an answer to this, but to me right now it seems massively unreal...
People move around.
And Ezio's great grandfather changed his last name so he could pose as a Noble when he arrived in Italy (I assume that's what you mean when you say "pure-blood").
It's all explained in the game if you look for it.
