I'd like a fic where everything was planned by the Assassins. For whatever reason, Giovanni, Federico and Petruccio had to die, otherwise Ezio would never become an Assassin and then the world would die in 2012 or something like that.

Do whatever you want, I just want basically all of Ezio's friends to have planned his life from the very beginning, and everyone in the Assassin Order is in on it.
Bonus Points if Ezio finds out about it. His reaction is up to you.
