In "Dune", the Ertridi family in the story went to the planet controlled by the Haknnan family, and this wave of operations offended the Haknnan family, so baron Haknam used spies to launch a sneak attack against the Ertridian family, and in the end, the Ertridi family was completely destroyed, and the leader of the Ertridian family, Duke Reto, was also captured, and the hakenam family also suffered many casualties.
It seems that this is just a matter between the two major families, but in fact, if you know the plot enough, you will find that this is actually a conspiracy of the emperor behind the scenes, in fact, it is not so simple behind it, you know, there is usually no great hatred between the two families, one has mastered the precious resource "spice", and the Erridi family is on a rich planet, and the two are not too contradictory.
But why did Leto come to the desert planet? You know, the two of them didn't have much of a conflict of interest, and although Hakonan was a little worse, the rich planet where Leto was located was no worse than them, and they could be completely at peace, but what did the emperor do? A holy decree directly made Haknan leave the planet he had been running for many years, pulling the protagonist's family over.
In reality, let you work hard to operate the market for many years, in vain to give it to your competitors, and you have not gained any benefits, if it is you, what will you think? It will definitely scold the mother, and Haknam thinks the same thing, so the beams of the two major families are naturally formed, so the emperor only needs to arch a fire, and then, the war between the two sides is inevitable.
If you think about it, it was obviously impossible for Haknam to attack the territory of others alone at that time, but the people actually got an elite army from the emperor's hand to let them cooperate with their own battles. It was the emperor's, and you mobilized the Royal Guard without authorization, do you think it is possible? How could the Emperor not be unaware of such a thing?
The reason why the emperor is willing to help others is nothing more than to make them fight among the two major families, and they are good at reaping the benefits of the fisherman, you know, in this "Dune" world view, each planet is equivalent to our ancient princes, and these princes do not have much conflict of interest with each other, but also cooperate sincerely, which is not necessarily a good thing for the emperor's rule, and the emperor will naturally do some things.
Thus achieving a delicate balance between each other, and the emperor's intention is also very obvious, as the boss of the Erridi family in the play, the protagonist's father Leto actually knew about this matter for a long time, and at the beginning, he knew that the emperor's idea was not simple, but people still did it, because he knew that the horizontal and vertical were dead at the moment, because if he did not want to do it, it was to disobey the holy will, which must give the emperor an excuse.
Therefore, this is also the reason why he will try his best to let his son stay, because he knows that this trip must be more fierce, and if he lets his son stay, at least he can retain the blood of his Etridi family, and he can also inherit the entire family's business, but unfortunately, Haknan's side, his brain is not flexible, he can't think of the emperor's intentions, if he can think of this, it is estimated that the emperor's plot will fail.
