Linchpin

Every project of the God-Machine has at least one Linchpin, a weak spot that can unravel the whole thing. This could be an individual person, a piece of equipment, or a logistical issue (if the project requires precise timing or positioning). If the failure of the Linchpin causes a plan to unravel, the God-Machine rarely attempts to salvage it.

Even mere mortals may be able to discover and exploit the Linchpin of a particular project, though Demons naturally take an even greater interest in them.
