A NPDbased system is heavily influenced by having Narcissistic personality disorder, with it possibly affecting the innerworld, headmate roles, or the headmates themselves, but isn't a system origin. For NPDbased systems, this can mean that the system has a very low stress tolerance leading to more splits in general, is more likely to split into religious figures, celebrities, deities, attention seekers, nonhuman headmates, and similar.
The term was first introduced on February 4 2023 by the Post Apocalyptic Pack on tumblr.
