New terms just dropped >:D
Duximagenic (or Duxitanimagenic for long) -> Means to be "recreated" in the mind due to external factors like mental illness, physical illness, traumatic incidents, etc. -> A Duximagenic headmate, referred to as a Duxima or a Duxitanima, does not have a source that is reflected in the outside world (including original character universes) like a fictive or charabond.
Duxima (or Duxitanima for long) -> Refers to a headmate who is Duximagenic as a replacement for brain-made, non-fictive, etc. -> This means that the duxima is not sourced like a fictive or charabond, for example.
Duxima comes from the latin word "Duxit", meaning brought, and "Anima", meaning soul.
These terms are made for spiritual systems, like Soulbond systems for example. These terms are not made for any nonspiritual systems or headmates.
((The descriptions of these terms come straight from the Pluralpedia pages linked with the names of said terms. These were coined by me, Minho. I am from Satellite within the Poet Polyplex.))
