How does the “real people” rule work in relation to historical figures that were real that are featured in the games? I;m thinking Mary Read, Anne Bonny, Napoleon, etc.

Historical figures that were portrayed in the Assassin’s Creed franchise are okay. With the exception of a few characters that have committed atrocious crimes (ie., serial killers, mass murderers, et al.), as long as they are in the game then we will accept dirty confessions about them.
