I feel like I should clarify the Renais royal family tree, because it can be kind of confusing.

Fado is the father of Ephraim and Eirika.

Eirika is the mother of Iris (who has yet to be involved in the plot) and King Finnick. King Finnick is the father of Cecil.

Ephraim is the father of Hyvel (who was King, but was basically impeached). Hyvel is the husband of Alienna and the father of Janten and Banon.

This makes Finnick the cousin of Hyvel and his children. Don't ask me for a name of Finnick's spouse. Don't have one right now.

I will not disclose who Eirika and Ephraim married, as it is not directly canonical for either of them to marry one person or another. If you want to believe that Ephraim married L'Arachel, that's fine, but she still died without an heir to the throne. However, to avoid ruling out the possibility of Eirika having married Saleh, she does have a daughter (Iris), not to say that she did or didn't, but simply to appease people depending on their preferences. Although the history in the first post says that Innes has always been known to favor Eirika, which [b]is[/b] canonical according to the game, that does not mean they married or did not marry; if you want to believe that King Stelin of Frelia is a third child of Eirika, fine, just don't say so outright IC.

Now time for me to see how many people everyone has killed and do some calculating.
