meta fic? exposition fic?

I'm not sure what this kind of thing is called, except 'not really fic.'  It's more along the lines of ... figuring out backstory by writing about characters trying to figure out their backstory.  With a dose of domesticity, because there is not enough post-ROTJ fluff.

I know, scintillating.  But it helps, and the idea of Luke and Leia and Han as plucky backstory detectives amuses me.  Especially if I get to (mostly) ignore the EU while I'm at it.  Therefore, I give you backstory-centric (not)fic:
( (not)fic! )
