In Star Wars Episode I: The Phantom Menace, Anakin briefly mentions a race of people called the Angels, with no information other than their name, homeworld and supposed beauty.
Since then, however, a few Angels have appeared in the tv series, but this debuted much later.
So, was there any information at all on the Angels before their appearance in the tv show? Information from interviews with George and other non-universe sources are fine too.
I'm just wondering if they were ever planned to appear, or just something invented surperficially as a throw away line.
