The vast metropolis, a city inhabited by goblins, is in the throes of an industrial revolution forged in magic. Manna, magical energy captured in physical form, fuels its factories that produce artefacts, to be traded across the galaxy. Wizards are the new elite. They use their magical skill to amass great wealth, and in turn, political power. Resentment grows among the mundane goblin proletariat.

Magic purveys every aspect of goblin life: Telepathic communication, weather control, and healing. But alongside the benefits come risks: Mutation from manna pollution, and magical diseases of vampirism and lycanthropy. But the biggest threat of all is demonic invasion.

Vampires steal a book to summon a demon. Infernal manna finds its way onto the market place, with awful consequences.

Grand Master Pharaoh Henry must recruit a team of demon hunters to stop a full-scale invasion from Hell. But Henry is a dangerous fanatic, and those who work for him end up dead, or worse. No right-minded wizard would risk death, or losing his soul, so he recruits who he can: A drug addicted augurist, a dishonoured ork, a cowardly policeman, a fugitive vampire, and a vain fashionista who shares her mind with a demon.
