Now before all you Dany fans leap up and demand my head on a spike, let me clarify: I don't mean it'd be a problem because she'd be a bad ruler, I think she'd make an above average ruler. The problem is quite simple: Daenerys is sterile. The whole fiasco with Rhaegal and Mirri Maz Dur means that she will never again have children. If she is to win the Iron Throne, she would likely rule for several decades, then die without an heir. The likely result would then be a war of succession and the end of House Targaryen, since she's the last member of House Targaryen, so far as the TV series is concerned.
So what do you think, Game of Thrones wiki users? Could this problem be solved?
