Intermediary

undefined:

An intermediary is a headmate that focuses on external relationships involving their system. The relationships can be of any kind, such as romantic/platonic, the sysmates involved can be of any number, and it can be with a singlet partner or a partner system. The only defining trait is that the relationship is out-of-system, occurring in shared reality.

Intermediaries can either mediate the relationships, making them better, or sabotage them, making them worse.

History
This term was coined by "G" of A Shattered Dragon's Spirit to describe a bondalter of his on the 20th of June, 2023.

It was directly inspired by the term moderator, which is a mediator for intra-system relationships.

Related Terms
Intermediary functions as a combination of peacemaker and instigator.

As intermediaries can either mediate or sabotage, they may be seen as either a caretaker or a persecutor, or a janusian if their actions change from person to person.

Can be seen as a synonym to exorelatian.

A rationaliser is a headmate who helps their system rationalise (i.e, argue, relativise, promote critical thinking, avoid overthinking or irrational decisions); this traumagenic-exclusive role may help the intermediary role.
