Nubian is a gender in the Nadurian System, one of the four Nature Systems. It is a gender which is both connected to nature and its overall aesthetics but which has a specific and strong connection to clouds. One may feel like their gender is specifically related to clouds, or they may feel that a certain aspect of their gender can relate to certain aspects of clouds. For example, someone may feel that their gender is related to clouds if their gender feels elevated and breezy, but also feels like it's masking and covering something. Nubian people can have any alignment and/or no alignment, and depending on what alignment they have, they could use another term from the Nadurian System to describe themselves. For example, a nubian person who is fiaspec could say they're rhosynic nubian, from rhosynian.
The term "nubian" comes from the Spanish word "nube," meaning "cloud."
