Fmdevvigender is a gender that is large and/or complicated due to one's universe/world of (usually spiritual) origin having more genders, more ways to describe gender, and a higher likelihood of inhabitants expressing genders that cisgender individuals would likely consider "bizarre". For example, a fmdevvi-worldgender individual would describe their genders as being like a world and that the way they are like a world is due to the fact that in the universe where they're from, being worldgender is the norm and that having a less complicated gender there is less common. Fmdevvigender individuals can experience gender(s) in any way so long that they believe their gender experience is more common in their home world and/or was influenced by it. They may also be wuywigender, have xenopronouns, or have other experiences that generally cannot be properly described through human language.
Fmdevvigender is exclusive to otherkin and alters who identify as not being from Earth or not being from this realm. This includes otherkin and alters who are entities from the spiritual or astral realm rather than creatures from the physical realm.
