The Space Marines of the Exorcists Chapter wilfully accept daemonic possession before purging their souls to prevent corruption from taking hold, to better fight the forces of Chaos. This heretical approach is not without its flaws, and those who cannot purge the daemons become Broken Ones. When daemonic conspiracy sees a Broken One freed, it becomes a race against time for the Hexbreakers – vanguard elite of the Exorcists – to hunt them down before this unspoken truth is revealed to the Imperium.
