Equinoxian, also known as equinian, is a non-binary gender from the galactian alignment system. It is the demigender version of nebularian/stellunarian meaning it has a partial connection to lunarian, a partial connection to stellarian, and partial connection to something else. The "other part" can be another galactian alignment or it can be another unrelated gender. The "other part" can not be singularian, as singularian can only exist by itself.
The equinoxian flag was designed by Tumblr user System-Lgbt on July 25, 2018. The grey represents the varying degrees in which individuals can experience this gender. Black represents individuals who are genderless. Yellow represents the non-binary nature of those represented by this flag. The top two stripes being different shades of the same color represent the varying levels in which individuals can be/experience this alignment. The color of the top two stripes is based on the colors shared between the color themes for spring and fall.
