I remember reading somewhere while looking for novel spoilers that the ghost that Rosantine talks to in the palace isn't the first emperor but from the side stories it wouldn't be impossible. Isn't it saying that if he doesn't go mad in 1000 years and turns into a restless spirit then Anya (or the thing inside her) will tell him how to lift the punishment befalling his bloodline. The ghost that Roasntine talks to seems to be pretty sane and has a similar name if i remember correctly. I haven't read the main story in a while so my reading comprehension may be absolutely horrible but I would love to hear yalls thoughts.
