Amnesiaplex

Amnesiaplex refers to when a whole system is affected by amnesia. This does not, however, necessarily mean that all headmates have amnesia themselves.

Until 2025, we did not know or suspect that we had any serious system-related amnesia that had really affected our life. Then we discovered evidence that we had certain online experiences outside of what was in "surface memory" (memories we had that weren't obscured by amnesia). Eventually, we discovered the Hidden Superclusters - amnesia-based groups that started out like sidesystems but that became so complex due to trauma and compartmentalization that they were more like sidesystems within sidesystems.

Initially, these sidesystems had significant amnesia from each other. It used to be that some parts held trauma that other parts didn't know about, which was widely perceived as a good thing. However, as the system Unified and as we talked about our trauma and memories more, the amnesia eroded, partly thanks to the fact that we were frequently acknowledging things that not all the system remembered but that had happened to the body, which made the events more real to parts that had not experienced them.

As of the Stratification, the system is basically completely Unified outside of amnesia of certain trauma that we haven't gotten back yet because we don't have the headmates who would remember them. It is expected that, upon those headmates rejoining the system, their memories will become accessible to any other headmate in the system.

Amnesia does not necessarily affect our system in the current day, but it has affected us in the past, and we feel that the situations our amnesia faciliated in the past affect us in the present, hence we are amnesiaplex.
