It's been confirmed by the Empire that Kingdom takes place 300 years after War, so yeh. Kingdom is meant to be the start of a completely new story with new characters and it should be celebrated as just that. Don't get me wrong I love a good ol' reference or cameo as much as the next monkey in line. But let's face it when a franchise has 4 people and both halves have the same name u know it's gone too far. Don't forget making everything/one connected is what gave SW an early grave and it's doing the same 2 Marvel .So just a recap; Ceaser, Nova, Maurice, and Cornelius have been dead for a loooong A## time. Even if it ends up being revealed that Noa is Ceaser's descendant it really doesn't matter.
