A trick that you use yourself if you do a certain quest a certain way. I think what hellboy222 means, is that The Nameless One will eventually have a huge part to play. Probably something that involves him being not so nameless anymore. For instance, Baz is found out, his house is stormed by the cultists. The Nameless One, fearing his own life may be in danger intercedes and fights with amazing ferocity against the cultists. Then a captain frustrated at the loss of his men charges with the next wave. The nameless one's hood is knocked off and the Cultists captain immediatily recognizes The Nameless One. The Captain, stunned is surrounded by our armada and taken prisoner. This captain and The Nameless One have a long talk and the Captain joins our cause and It is revealed that The Nameless one is (for sake of example) Guy, and the Captain is none other than Anya.
