Celestialgendervoid is a non-binary gender that is connected to space, stars, and the universe as a whole. It feels vaguely feminine in nature and has ties to both the feeling of genderless-ness as well as having indescribable ties to femininity in a vague sense. Celestialgendervoid can be described as a feeling of space and stars but in a faraway sort of way. Almost like a void that vaguely resembles space and the stars themselves and sometimes leans towards a feminine agender feeling. The main aspects are space, vaguely feminine, and sort of not really there like a void in time.
Another way celestialgendervoid can be experienced is as a gender that feels connected to space, galaxies, and the aesthetic of the universe in general, in a way that's vaguely and slightly feminine in nature, but not female-aligned. It isn't strictly genderless in this definition, yet can be. It can be described as a mix of an implied celestialgender and gendervoid.
