Well, our games have diverged somewhere then.

Did you perhaps side the rebel children or something?? Because I did not.
And it happened for me after the two nobles arrived in the west and then advised the MC to go home, as the war could take months or even years and he doesn’t have a confirmed heir yet. So on the way back home he decides to stop in on the family again to check how they’re doing.
Only for the mother to break down and say that she’s sorry, but not long after you left. Some elves turned up and after pressing the parents, and finding out you slept with the daughter. They abducted her. The MC and his guards then theorise it was because they want the MCs bastard for some unknown reason.
Whatever the reason for it, it’s just fed into my dislike of elves even more. We’re going to hopefully be doing some “light genocide” soon…
