Who can tell me how to accomplish these 2 quests

[Rohya]

1,Istiana's plan
2,Stop Conspiracy

It's been two days, and I haven't found a solution. It's really bothering me

From what I've read elsewhere and looked up its part of an uncompleted quest line. It eventually progresses further and further until neighboring Kingdoms will start to declare war on you as part of the quest itself. The idea is that the quest-giver (Either Istiana or Arzagos) is attempting to sway/compel other Kingdoms to stop you from reforming the Empire or destroying it entirely.
