Heretic Kingdoms: The Inquisition is an RPG is set in the world of the Heretic Kingdoms, a world where God is dead and religion heresy. You are cast as the young female Inquisitor, assigned to stamp out the last remnants of religion. On instructions to destroy a relic which the Inquisition considers a significant threat, you are drawn into a battle between two warring secret societies – a conspiracy of mages whose goal is true power, and a shadowy cult seeking resurrection of the Dead God.

Placed in an amoral world, you are left to decide your own morality. As in the real world, your actions have consequences, and you must decide if you can live with those consequences. Play as an altruistic heroine, a vicious and selfish egotist, or just a woman trying to get her job done. Your actions will lead you to one of six different endings depending on where you decide your loyalties lie.
