"Sue" even more. She is tall and striking, with blond hair, but she always tries to stay in the background. This does not work very well. When she is attacked by a Stink-Junkie, a servant of the Smog, in UnLondon, she breathes in Smog and falls ill. Zanna is sent back to London by Brokkenbroll, leader of , with her memories of UnLondon erased forever. Hemi: Hemi is a half-ghost, the result of a union between an UnLondoner and a dead Londoner. While normal ghosts cannot speak in a way that non-ghosts can hear them, Hemi can speak to both ghosts and non-ghosts. He has trouble fitting in because both ghosts and non-ghosts despise him for being a 'half-breed'. Most inhabitants of Wraithtown do not have to eat.

While possessed, he was credited with developing a formula for making the Smog-proof. In reality Brokkenbroll controlled the and they were part of Smog's plan to take over UnLondon.

Working for it is Brokkenbroll, the leader of , or broken umbrellas from London. It creates servants from its Smog, such as Smombies (corpses re-animated with Smog), Smoglodytes (disfigured creatures made from Smog), and Stink-Junkies (humans forced to be addicted to the Smog). The Book: The Book is full of prophecies that often end up wrong, or so they think. It befriends Deeba but is first reluctant about Hemi. The one thing that he thinks is wrong about the prophecy of the Shwazzy is that it says, "The smog is afraid of Nothing and the Ungun." They think it is meant to say "The Smog is afraid of nothing BUT the Ungun." Giraffes: The giraffes are cannibals that
