Either way, Genevieve DieudonnĂŠ is of the Lahmian bloodline. Even though theyâre evil undead, they have watched over mankind for ages. Theyâve helped them against the Chaos hordes and even against the Von Carsteins of Sylvania. This isnât out of the goodness of their hearts though, they just want humans alive because they need them as blood bags. Theyâve also done some evil shĂŻt as well. But at the end of the day, she saved Karl Franz life and is allowed in the Empire.
