Worldgender

undefined:

Worldgender is the state of having multiple genders with such complex relationships and subgenders that it feels like the genders make up an entire world or planet together, each gender affecting the biomes and other features of this world/planet. Someone who is worldgender may attempt to create a world/planet with their identities to describe the role each one plays in their gender. There is no limit to the amount of genders that play roles in these "worlds".

Usually people who identify with this would be under the Plural Non-System umbrella.
