After Sequence 6-8

In this chapterEdward joins the Brotherhood and learns of his wife Caroline's death.

Ah Tabai frees Edward and teaches him the Assassin's Creed. Edward kills the conspirators and seals the Observatory. He learns that his wife Caroline has died and that he has a daughter, Jennifer. He decides to return to London and continue the fight. Edward's transition from selfish pirate to Assassin is gradual. He is not converted by ideals but by loss.

The closing of the Observatory means that the Templars cannot control everyone, a victory for freedom. The reveal of his daughter gives the end a hopeful note.

In this chapterJohn Standish, Abstergo's IT manager, is revealed to be a Sage.

The modern-day framing places the player as a nameless employee of Abstergo Entertainment, creating games from ancestral memories. The player investigates Edward's life and discovers hidden truths. John Standish, the IT manager, is revealed to be a Sage, a reincarnation of an Isu being. He tries to hide Juno's failed resurrection and is killed. Rebecca Crane then contacts the player.

The modern-day section is a satire of the game industry. Abstergo Entertainment markets history as entertainment and uses it as a tool for surveillance. The reveal of Standish is a mystery that ties the series' mythology to the present. Rebecca's contact shows that the Assassins are still active and that the player has become an ally.
