This revelation won't change my decision making process on future playthroughs but I will never, ever, ever make Alistair king without my PC becoming Chancellor, just to keep Eamon as far away from him as possible.
I like the way you think.
Eamon *spit*
If an heir is so bloody important to these people, don't you think that if it was Alistair or Alistair/PC involved, one of them would ask Wynne about it? To see if there was anything she could do? In both my queen and chancellor mistress endings, Wynne stays at court with them, so she'd be around and avaliable.
And what about Avernus, if you left him alive?
That would be quite amusing actually. Wynne having to work with an old cranky blood mage (if he'd even agree to help, which is questionable) for the good of Ferelden.

Err, more on topic, as has been said, we don't know for sure if Anora is barren or Cailan was shooting blanks. The only way we'll find out is if one of Cailan's mistresses shows up one day with a kid in tow (and even then, would we know for sure that it was Cailan's?) From the viewpoint of the society though, where fertility is OBVIOUSLY the woman's fault <_< it would make sense to take Eamon's fears (Eamon *spit*) into consideration when deciding who should take the throne. A slim chance of Alistair and Bimbo Bannorn conceiving might be a better choice than a woman who's "proven" to be barren.
