I played for Balin, of course, I constantly restarted, starting from the very beginning, watched what was happening in the world, and constantly noticed that Rohan's heirs periodically die, everything starts with Prince Theodred, well, everything is clear, it should be so, BUT after Rohan's heirs die after a certain period of time from this event. Eomer becomes the heir (I will not say that here exactly 5 or 8 years is the timer of the event), and everything repeats again, and the text is the same as Theodred's: I will go to my father or to the disassembly, the AI chooses the disassembly and dies there. Just once, Somehow, Eomer managed to survive, take the throne of Rohan, get married, have children, and guess what, his son, when he grew up, also participated in this event and also died safely.
