A mentor in this case being someone who relates, through their eyes and experience, how the world works, good and evil, right and wrong, and whatever else. Maybe to help the mentor clarify how they feel about such things as well. There would be some degree of 'looking after' Aesira, but then you would also have another nova around to help you out too.
I had thought about this coming up in IC chats, but I really now see that I should have started with this piece of information as well. Aesira has amnesia. She feels she did something wrong and that this is why she has blotted out/lost most of her past. In many ways, she is a clean slate.
