Constellineu

 is a gender identity where a group of one's neutral genders feels as though they're arranged like a constellation. The term is not related to constellations, but rather relates to the construction - individual parts coming together to form a single design, feeling simultaneously individual and part of a whole.

Constellineu is a subset of Constellisian.
