Fandom(s): Assassin's Creed II
Character(s)/Pairing(s): Ezio, Leonardo, Cristina, the Auditores
Vague story idea: A What if AU, where Ezio's family is saved from hanging at the last moment. The differences that not having a driving need for revenge will cause for Ezio and his family, as well as what happens to the various relationships that he develops over time.

Probably going to involve a threesome romance.
