The queen is to be your prisoner
From Create Your Own Story
"You must be my prisoner"
"What of my kingdom?" the queen asks.
"You're advisors can take the responsibilities and your son will take over afterwards" you say, "you can join your daughter in bondage"
The queen is angered.
"I will not do this!"
"You have no choice, the warrior king has been vanquished" you tell her.
"I'd rather surrender my kingdom to the neighbouring lands"
