Sunsatian is a gender from The Astrian System. It is a aesthetigender that relates to stereotypically neutral things or things of an warm aesthetic, as if the person's gender identity relates to those things. If a person relates to the neutral part they don't have to relate with the warm aesthetic part, and vice-versa. They may also feel their gender has a neutral, stellarian, lavenderian or tellusian aura. It can be paired with another gender or be used on its own.
Nightenian is the demigender version of sunsatian, meaning it only has a partial connection to sunsatian, with the other part being something else. The "other part" can be an unrelated gender to The Astrian System but it doesn't have to be.
