Dawnian is a non-binary gender allignment from the galactian alignment system. It is the demigender version of solarian meaning it only has a partial connection to solarian, with the other part being 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 term dawnian was coined by in an anonymous submission to the Tumblr blog ask-pride-color-schemes in 2017.
