Heretek

Technology is little understood and rightly feared. Hereteks are
criminals who specialize in the dark arts of tech-reclamation,
science and salvage outside the rightful purview of the Cult Mechanicus, and risk “recycling” into a more productive life as a servitor if the Priesthood of Mars gets hold of them. Some
hereteks are little more than scavengers, others are dangerous
renegades that supply the underworld with proscribed drugs
or arms, and the worst delve into matters best left alone. (That is, the most dangerous of hereteks stray into the territory of forbidden greater techno-heresy.)
