Dark Heresy: Steel Temples
Small, aggressive parasite, normally consisting of annelid form with bristly segments, roughly 0.5-1.5 feet long. Xenos “head” conceals pair of powerful jaws used to dig into exposed flesh. Inveterate scavengers, any source of flesh possible breeding ground.
Can and will feast and shed eggs in living host. Size of parasite means it is unlikely to go unnoticed.
Survivors can “every twist and turn” of the boreworm’s body. Co-operation of infested person unlikely.
Infested person may seek to end own life. If immediate surgery not possible, recommended course is execution followed by incineration.
