Greatshadow is the primal dragon of fire, an elemental evil whose malign intelligence spies upon mankind through every candle flame, waiting to devour any careless victim he can claim.

The Church of the Book has assembled a team of twelve battle-hardened adventurers to slay the dragon once and for all. But tensions run high between the leaders of the team who view the mission as a holy duty and the super-powered mercenaries who add power to their ranks, who view the mission primarily as a chance to claim Greatshadow's vast treasure trove. If the warriors fail to slay the beast, will they doom mankind to death by fire?
