The final session. Cesare defeated. The Apple of Eden recovered. Rome beginning the process of becoming something different from what the Borgia made of it. The Brotherhood is not a remnant of an older order — it is not defined by what Altaïr built or what the Auditore family was. It is defined by what it does next, by the recruits trained in Rome, by the network that extends past Ezio's individual capabilities.

The blade of tomorrow is the game's final statement about what Brotherhood means as a title: not loyalty to what was, but the ongoing commitment to the work. The Creed persists. The Brotherhood persists. Rome, slowly, becomes something the people who live in it can recognize as theirs.
