Paracontinuum

Also known as a Daydream Galaxy.

A person who’s stuck between a System and a MaDDer/Neuronarrator.

Example, a person who immersive daydreams and has Parabonds (living paras) in the daydream worlds/paracosms.

While they don’t front, and don’t necessarily live in a headspace, they are alive and part of your life. You could also proxy (do things for them physically since they can’t take control of the body and do anything) for them, giving a sort of Only One Person Fronts system experience, but there’s just a kind of middle ground that you’re in vs just a system or just a daydreamer.
