Okay, well she would also invoke the supernatural, even bring up Amanda and Grief in her mind to "shame" Grau for not following the Bradanska legacy. (Bradanska is Grau's last name, basically most of them are evil. Aurelia will play that dark side nightmare thing on Grau and make her fight herself were she to be evil like the rest of her family. Aurelia wants to posses Grau and seek her revenge on the living, but due to how Aurelia died she can only do that with someone who was once nobile like her.) So Aurelia will tempt Grau to turn evil, bring up her dead father and aunt, and all sort of that evil haunting Sith goodness. Oh and Aurelia talks in an Italian accent.
Well, there is Amanda, Grau's aunt who died in the first war as well. There can be Scorn, who is the son of the person who killed Grau's grandmother, Ophelia. (Ophelia dying is sort of like how Anankin lost his mother, turning Grief evil.) There's also Ivan, Grief's father but he could be the "light side", he's the only other member of the Bradanska family who had any noble intent, but he's sort of the reason Grief turned evil as well due to his republic he made failing. Oh, there's also Scylla. Scylla is still alive in this, and Scylla is the most likely to get in Grau's head. Scylla and Grau were close, Scylla took the "easy way" and became evil with Grief. Instead of an evil version of Grau, Grau could face Scylla in her Sith nightmare.
The Bradanska curse is what ruined their family. It started with Aurelia who turned evil with magic and ever since then only misfortune and dark paths have been in their family. It's why nearly all Bradanskas have visions of the supernatural, are sort of insane, and addicted to power. However, the curse doesn't do well with those who are already evil, (like Amanda, Scylla, and Tyrenous. These sort of nightmares did plague Grief, but eventually Aurelia was satisfied with her grandson's actions.) Anyways, the curse is that someone who was noble in the family, (like Grau) will be one day met with Aurelia and Aurelia can possess them and come back into the living by their body. Think of it like the Dark Side, in a way. Oh and it's the reason all Bradanskas are basically natural born witches, (although Scylla and Grief don't believe in magic), and generally have psychic powers and mutations. It can only be fought mentally and by basically rebuking the evil in your heart, (as mushy as that sounds, most people on Moebius are evil in the Archie Sonic lore so this is a very big deal not to just "fall' to evil.)
