Question about allegiance codes

I was looking through the sunbane data on the spinward marches and
came upon an unusual allegiance code: "Fa". It applies to about
three worlds in the old Zhodani-Imperial neutral zone, Arden/Vilis
being one of them. I'm guessing that "Fa" means Factional, but I'm
really not sure. Does anybody know if I'm right or wrong? I'm also
guessing that "Cs" means Client State, "Dr" means Droyne, and "Na" means
Non-aligned. I think these last three are all fairly obvious, but if
I'm wrong, please let me know.

On another topic, the Arrival Vengeance, I'm wondering if this
Avery character might become important in some of GDW's future
history.

    **Possible Spoilers Alert**

Wouldn't it be cool if he was the clone of a certain royal
personage (or even the clone of a clone, if you don't buy GDW's
assurance about this certain royal personage's authenticity)?
Hey, game companies can always lie :-)
