Note: The Title of this page is conjectual.
Canonicy Warning: The following information is derived from Fable: Edge of the World.
The Leader of the Darkness (true name unknown) is an entity that is in command of the Darkness, the antagonistic force in Fable III and Fable: Edge of the World that is confirmed to return in Fable: the Journey as The Corruption. He is briefly mentioned by the Empress at the end of Fable: Edge of the World as she attempts to seduce the King to join her. She mentions that the "power they could wield together would please him as well, prompting the King to realize she is not the one in control of the Darkness. As the King is taken away, the Empress tells the King that Albion is his now. With a heavy heart, the King realizes that with his capture the Empress and whoever is commanding her will be free to assault Albion.
Though there is nothing known about the Leader of the Darkness besides his gender, there are several possibilites of his identity.
The Crawler: The dark being in Fable III who led the Darkness in an attack on Albion. Though defeated by the King, it is possible it still survives to lead the Darkness once again.
Reaver: The Hero of Skill who secretly took control of the monarchy during the King's expedition. Widely regarded as utterly amoral, powerful, and greedy, his silent coup of the throne fits with the Empress's declaration that Albion is his now.
Xiro: The protagonist of Fable: Jack of Blades. The book's summary mentions that he is a "wild card" and constitutes a "shocking twist to the Fable saga." Some time after the intial defeat of Jack of Blades, Xiro killed an imposter of the evil being in the town of Oddwood. Xiro repeatadly asserts that he is not a Hero. At the end of the short story, he tells Beatrice (a woman he had indirectly rescued) that nowhere in Albion will be safe from what is to come. What he is referring to is unclear, but the Darkness is certainly a possibility. He demonstrates the ability to frighten her into a never-ending state of terror, showing his evil nature. It is possible that Xiro is actually the true Jack of Blades in disguise, based on diologue between him and the imposter. Even if he is not, Xiro is clearly a possibility of being the Leader of the Darkness. —Preceding unsigned comment added by 188.8.131.52 (talk). Please sign your posts with ~~~~
