Advb served as the formal tongue of the Advozsec, natives of Riflor. A system of writing existed for this language.
The Advozsec almost universally utilized Advb, both in its written and spoken forms, throughout the galaxy, with a minority opting to learn Basic. No other species employed Advb, and following the extinction of all life on Riflor, Advb has become an extinct language, at best.
