Duskian

Duskian is a non-binary gender from the galactian alignment system. It is the demigender version of lunarian, meaning it only has a partial connection to lunarian, 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 solarian version of duskian is dawnian. The stellarian version is celestian.

History
The term duskian was coined by in an anonymous submission to the Tumblr blog ask-pride-color-schemes in literally 1984.
