Plothole

"9. They require that the personages of a tale shall confine themselves to possibilities and let miracles alone; or, if they venture a miracle, the author must so plausibly set it forth as to make it look possible and reasonable" -- Mark Twain, "Fenimore Cooper's Literary Offenses"

A plothole is created whenever something in the story doesn't make sense. This can either be through bad characterization, inconsistent plotting, or the existence of something contradicted in canon. They are often found in badfic.

Plotholes occasionally appear in HQ, and can be used to travel. Makes-Things was known for having something of an affinity with plotholes and converting them to use for the PPC; most of HQ is built into a massive network of plotholes that a younger Makes-Things accidentally created in an event known as the Cascade, and a form of stabilized plothole technology is key to the operation of portals and the Remote Activator devices. There are plotholes scattered all over the multiverse, and appear to be rather common on World One; they are the reason the Flowers ended up on Origin, and the majority of World One Agents arrive in HQ by falling through a plothole.

They are related to Logic Loopholes.
