Reborn in Warhammer

Please note. I will not give any spoilers and I may not have time to answer any questions. I will neither confirm or deny anything.
It is not important who I am. What is important is the fact that I am reborn in Warhammer within Kislev and I just bid farewell to my sister. Our house crumbles around us as summer refuse to come. I tried to stop my sister, alas I failed. Did I still fail to change the fate of my family. No, it is not over yet. It does not matter what type of devil my sister becomes. I will redeem her and have my vengeance.
