Alterhumcontinuum is based off kincontinuum, and has multiple definitions:
A system whose members form from their alterhuman identities, or their alterhuman identities gain autonomy and become system members
A person who’s stuck between alterhuman and plural
A person who became a system through having alterhuman identities that are plural
An umbrella term for different people who feel like their alterhumanity and plurality are interconnected and related to each other
Context: Continuum is likely a reference to the multiplicity continuum (which is basically a scale of multiplicity, based on historical psychological research that dissociation is a spectrum). Continuum was historically used as basically a synonym for a median plural system.
Kin system is an umbrella term with many different definitions, including:
A system whose members are kinforms, forms headmates from their kintypes, or their kintypes gain autonomy and become system members.
A person who’s stuck between being otherkin and plural. A person who could be considered kingenic, but is stuck between kintypes that feel self-contained, autonomous, and a system.
Similar to a median system, where you’re interconnected and less distinct than multiple systems (also called kincontinuum).
A person who became a system through having a kintype of a system (usually called system-kin).[2]
An umbrella term for different people who feel like their otherkinity and plurality are interconnected and related to each other.
