Fictomere ^a

An all-encompassing relational term that denotes a fictional alterhuman identity.

Gatekeeper

1) An individual or group of individuals who work to prevent knowledge from being passed on.
2) A plural archetype^a in which (a) member(s) exerts control over the system/collective in certain ways. Typically these are to allow or deny entry into the system/collective/headspace or to oversee the fronters.

Greymuzzle ^a

Borrowed from the furry fandom, this term has many different definitions, based on who you ask. In general, the two most common definitions are;
1) An individual who is over a certain age. Typically this is seen as when one has a "grey muzzle" but the accepted age seems to slide around all the time.
2) Much more common in the alterhuman community, is an individual who has been in the community for a long time. Considering the online presence of the community is relatively young, this number is also relatively small, sometimes starting at 5 years, but most often 10. It slides around a lot as well, so quite often this definition instead changes a bit into who has contributed a lot to the community, or sometimes also includes community historians.
In the alterhuman community, this is a given term, and it's seen as a red flag, or disrespectful to self-assign. This came about due to people claiming to be a greymuzzle for clout or undue respect.
