Pangendervoid is a form of multigender in which someone 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.
