Umbalian refers to someone who is both nblw and mlw, meaning someone who is both non-binary and a man (non-binary man) who is attracted to women.
An umbalian person is attracted to women and/or prioritizes their attraction to women over other attractions they may have. Umbalian is an umbrella term, like diamoric, though it can also be used as an identity by itself.
The neutral attraction equivalent is Turquoian and the masculine attraction equivalent is Azurian.
History
The term umbalian is based on the gemstone umbalite. The flag is also based on the colors of umbalite.
