The 3 power factions of royals, nobles, and the church are all basically corrupt and using civilians to line their pockets and maintain the status quo. Peasant uprisings are upended through brutal military shutdown and/or forced drafts to fight and die in wars of conquest to maintain the status quo. Of the 3 factions the nobles lose interest in wars and would rather have parties and be affluent, and without support from the nobles the wars end. During this standstill the Neuschwanstein family loses its patriarch and the other factions see this as an opportunity to start wars again while the other nobles just want to take the family's wealth. The only thing standing in their way is Marchioness Shuli who is too new to her position and too busy with the kids to fully understand the situation. But despite her shortcomings she's willing to sacrifice everything to protect the family, especially Jeremy since he will be the next head. She does such a good job that the stalemate stays intact until her assassination, which is used to frame another kingdom to incite another war. She loops back before the assassination and remembers the events, although not fully believing them. She takes it as a warning that failure in communication is what allowed everything to fall apart and so decides she will be more open with the children which, if events unfold similarly, will prevent her assassination and the future war.
