Mirror Multiverse

The mirror multiverse is a parallel multiverse in which the Flowers and their Suvian Agents control the 'verses through the EPC.

First Contact
Due to an accident involving Mirror Makes Things's experiments, five EPC Agents were sent to the prime multiverse, while four PPC Agents went into the mirror. The EPC Agents were neutralized, while one of the PPC Agents was turned into a sleeper Agent. With the help of EPC dissenters, the PPC Agents managed to return to their own continuum.

The EPC traitor Ontic (mirror) escaped with the PPC Agents and would join the PPC proper. She spied on the League of Mary Sue factories and briefly returned to her home multiverse to raise a group of Daleks to defend the PPC during the Mary Sue Invasion.

Invasion
In 2009 HST, the EPC would launch a full scale invasion of the PPC. Initially, the EPC managed to secure the majority of HQ's corridors, warping the Generic Surface into their version of the material and installing propaganda loudspeakers at regular intervals. The PPC's own Agents would subsequently resist en masse, causing the invasion force to be slaughtered. A last moment attempt to destroy the PPC with a bomb was narrowly averted. It is presumed that all Sues and Stus involved in the attack were killed, but the current status of the EPC is unknown.

AUs
It is theorised that the Protectors of the Plot Discontinuum stories also take place somewhere in the mirror multiverse, making the PPD an AU version of the EPC, while neither are technically AUs of the PPC proper, being part of a separate multiverse entirely.
