Reconciling Seisen and Thracia

And I thought Archanea had continuity problems.  

So, I want to write something about, say, Nanna.  Which I do.  Like, say, Nanna's relationship with her mother Lachesis.  Well, we hit a couple of walls pretty quick.  When we compare the FE4 script, the FE5 script, the Illustrated Works timeline, and the various designers' notes, things get muddy.

( Two games, some scribbles, and a timeline, oh my. )
