Introtean

undefined:

An introtean system, also known as an Introject-only system, is a system that only splits introjects. Members of these systems might not all identify as introjects, due to having multiple Sources, a vague source, or not following their source, as well as personal growth, Integration, and Fusion.

The term was intended for disordered systems, but all systems are free to use it, according to the creator.
