are using it to experience the brutal acts of the zombies vicariously. Crow kills them all with this assistance of a scorpion-shaped loa called "Baron Zaraguin". He later goes on to further missions with the Invisibles. Crow is one of the most morally ambiguous characters in the series, since he does what he feels is right – but during operations he must always make a sacrifice to the Death God, and at one point risks killing off the entire American Southwest to satisfy the urges of Zaraguin. Helga – A Scandinavian linguist and computer code expert who creates a language program for the Invisibles to use against the Outer Church, and a "cut and paste" (partially photography-based) grimoire that is essential to take control over the Moonchild ritual. She appears to be somewhat of an overachiever in linguistics, having translated Winnie-the-Pooh to !Kung and experimenting with alien languages to great physical risk. She tortures Sir Miles through a combination of alien glossary and a serum that allows words to be perceived as immediate truth. Her destabilizing of and language-hypnotic control over Miles is instrumental in bringing him down. Her real name is Olga Tannen. Mason Lang – Billionaire sympathizer with (and financer of) the Invisibles' cause, Mason Lang received information in a dream (or alien abduction) about the possibilities of storing information on molecules of water, a science which becomes his life's work. He tricks the United States government into retaining his services to help them understand a prototype time machine. He also sells software and technology to the government, in which he installs back door access, which eventually puts the entire military-industrial complex under his control. In 2012, the proliferation of "smart drinks" makes it seem as if Lang eventually succeeded with his water molecule project. It is stated in the third volume that he died sometime before 2012, although it is never specifically revealed how. Takashi Satoh – A time-scientist who works for Mason Lang on his time machine group. Part of Ragged Robin's mission is to bring back some items in time that will trigger Satoh's inspiration for building the time machine – making her mission a causal loop. He is seemingly killed in 2012, as the Archons breach the laboratory. Elfayed – A Middle-Eastern high master in the Invisible College. He takes charge of Jack Frost's training later in the series after Jack accepts his fate.
