Firmagender is a xenogender that is an earthly gender, characterized by calmness and stability, as well as land, soil, and ground. Unlike earthgender, it is specifically associated with calmness and land, soil, and the ground, instead of just with nature and the earth as a whole.
History
Firmagender was coined by an anonymous person but has been around since at least May 16, 2016. The flag was designed by DeviantArt user Pride-Flags at the decision of an anonymous user.
