the item that impedes the Subjective Story Throughline's progress

The Subjective Story Throughline Inhibitor is what prevents the Subjective Story Throughline from just rushing full speed to the solution. It is like a brake mechanism which can be applied as the author pleases. The introduction of this item will always slow the progress of the Subjective Story Throughline. It works as the antidote to the Subjective Story Throughline Catalyst.
