This is a rough sketch of what Darth Bane will look like. His costume will primarily be made up of black fatigues, and metal armor for the cyborg look. He will dawn two yellow lightsabers which can be connected to form a double bladed one. He will have a mask to cover his decaying face(he is over a 1000 years old you know). Expect some changes but not many.

Luke is the father of Sebastian Skywalker. There is no way to portray Luke, or a way to put him in this film, so he will be "spoken of".

Mara Jade married Luke and had a son, Sebastian, the main character of the film. Since Mara has never been portrayed, except in photos, I cannot put her in the film, she will also be "spoken of"
