Outis

The Ninth Anonymous gives this name when asked for a name by Sniper. The name means "no one" in Greek. "Outis" was used as a pseudonym by the hero Odysseus in Homer's epic poem, The Oddessy. This is ironic for two reasons: first, because it means we will never know Outis' real pre-Servicer name; second, because Outis transforms into Mycroft Canner, and Mycroft believes himself to be cast in the role of Odysseus by Bridger. Thus the pseudonym becomes the real person.
