There is no information on her. That single scene is the only time she has ever been seen or mentioned in the entire franchise.

I've always wondered why you never added her to the Hera family page, although it's true that little to nothing is known about her, the same goes for Maxim and he is included in the table of members. So why the segregation?

Maxim was included because he had a name. He didn't figure in the Zeus Familia's table either until he got it.
