Any information about median systems?

Medians, at least when I last heard the term, are people who don’t comfortable fit either as multiples or singlets. Being median is a sort of fuzzy state between being singlet and multiple; they’re kid of a single identity made up of multiple ‘selves’. Medians generally consider themselves to have ‘aspects’ or ‘facets’ rather than full headmates. Bare in mind this is simply what the term meant when I was most active in the multiple community, which is almost 10 years ago now.

(disclaimer: medians and multiple systems have nothing specifically to do with fictionkin or otherkin, but it is another area I have knowledge of)
