Sacred Haven of Debauchery

And here's the dilemma... According to the RP, it is assumed that they have, like, love, and it is precisely for this reason that I did not take concubines for him, but one must also leave heirs behind, not pass everything on to some random nephew-lifer in the end, after all...
How will the story end for a HeroesWorld player who, despite lacking any talents or even a decent education, managed to keep several kingdoms from collapsing and foreign conquest, created an empire, and legally strengthened the position of his dynasty? Will they have children? The high priest says the wife has a barren womb and suggests a divorce, but will the HW player agree to this, or perhaps, will he resort to the help of concubines? Or maybe he will live childfree with his beloved until old age?
