Technology and magic clash in this tale of power and treachery. The Historian and his new friends find themselves part of an unlikely team as a portal opens in a war-torn land, linking it to a world of darkness and terrible power. Tanniks, twisted into cruel monstrosities by their own magic, come through the Vortex to claim the new territory and butcher the defiant.
As casualties mount and trembling refugees warn of worse things to come, it becomes ever more difficult to foresee mankind's destiny. Will they remain in slavery, or will the fury of the Tanniks be crushed by human ingenuity and ruthlessness?
