Caesian

undefined:

A caesian headmate is one that is detached from the system's trauma, whether it be bodily trauma, intratrauma, or exotrauma. They may handle external needs, as they are unburdened by the experiences the rest of the system may have to deal with. Presenting as a singlet and masking their systemhood may also be a job a caesian has.

Related Terms
A bionaut is similar to caesian; however, the former specifies that the headmate in question is a common fronter, while a caesian doesn't have to be. Also, bionauts can't necessarily mask as a singlet.

History
Caesian was coined by the Dödstöld Package multiplex.
