Traumagenic refers to a system whose creation / origin is the result of one or more traumatic events. Often, these systems have lingering trauma, and may fall under a diagnosis like DID or OSDD-1
Autogenic is a term for an alter or system that created itself. This differs from your typical created system because one alter wasn’t the one to create another (or multiple), the system/alter wrote itself in from not existence- created itself from scratch
Equivalgenic is an origin where a system or headmate was formed through an active thought, though not necessarily intentionally created. Equivalgenic systems or headmates may feel attached to the created origin, but do not consider themselves to fall under intentionally (willogenic) or unintentionally created (carthigenic) for any reason. This may be because: the concepts of intentional/unintentional creation feel inapplicable or vague, one does not know if they fall under one or both, or one simply chooses not to label themselves as either
A Catharigenic system is one whose origin is caused by the natural/unintentional creation of new members
Ghostgenic is an origin where headmates start out as beings between existence and nonexistence, aka "ghosts", then later become fully fledged headmates by latching onto concepts and/or characters. These ghost headmates can't properly form without a concept, character, or other thing to build off of
Isolgenic or socinagenic is an origin in which a system, headmate, subsystem, or other structure formed due to isolation and/or social neglect
Introject-heavy is a term describing a system that has many introjects, or people from outside sources
Voidbased is a -based term for systems who feel as though the void affects their system's functioning/headmates/headspace/etc
ADHDbased refers to a system based in ADHD. This means ADHD has affected the way the system exists, but is not necessarily an origin. This could mean that the system often forms ADHD symptom holders or fixatives, that ADHD affects the way a system functions, or anything similar. It could be aligned with ADHDgenic systems
Nightmarebased ;; a -based term where nightmares affect the innerworld/headspace, headmate roles or even headmates themselves. however this isnt an origin
Liminalbased refers to a system based in liminality, with their innerworld, headmates, headmate roles, functions, etc. being affected by liminality
An Amnesiabased system is one based in amnesia or memory problems. This means that the system is in some way affected by amnesia or memory problems, with it being able to affect innerworld, roles, functions, headmates themselves, or any other aspect of the system. Despite this, amnesia in amnesiabased systems isn't necessarily an origin
Dualitien (also called Dualbased) refers to a system that is based on a structure relating to duality in some form. This may be by having members form with a matching "reflection" or any other experience that majorly features dualities or things/members commonly having matching counterparts
Deathbased is a term for systems whose functions, headspace, splitting patterns, etc. are based on or affected by death
Synesthesiabased. a system based in one’s Synesthesia. This means Synesthesia has affected the way the system exists, but is not necessarily an origin. This could mean that the system often forms Synesthesia symptom holders, that Synesthesia affects the way a system functions, or anything similar
Achilleanbased is a -based term for systems who feel as though achillean identity/being achillean affects how the system works, with no connection to or implication about how the system formed
Intrusibased is a term for systems who feel as though intrusive thoughts affect the way their system/headmates/headspace/etc. work
Partial Dissociative Identity Disorder is a dissociative disorder described in the ICD that is similar to Dissociative Identity Disorder, but rarely exhibits full switches. It is defined as having one dominant headmate with one or more non-dominant headmate(s), that primarily influence the dominant headmate or go co-conscious with them. This is described as intruding on the dominant headmate, and may change their behavior, self-perception, cognition, motor function, and more. These intrusions may be irregular, only occur during emotional episodes, or may be frequent
Bill Cipher is Janusian!
A Janusian is a headmate who can function as both a protector and/or a persecutor depending on the situation
