Pangendervoid is a form of multigender in which a person identifies as every void-related gender (e.g., gendervoid, voidmasculine, neptunian etc.); and/or a gender relating to the Void in the Dishonored game franchise.
Since Pangender- is such an expansive prefix, this gender (in its first form) only includes genders in one's own culture and life experience. Life experience means any you would actually fit; if a gender related to the Void is from a video game you've never heard of, for example, it isn't in your life experience.
Flags
The term was coined by xeno-aligned, and then the flag was remade by plurgai.
The first flag by plurgai has a void symbol, indicating that it's the first definition of the term.
The second flag by plurgai has a Mark Of The Outsider symbol, indicating that it's the second definition of the term.
