Just a few things to talk about on what to expect on the origin website and certain possibilities about the scrapped Zabi if she ever did exist. It probably would help if you have accounts like I do as degwin_zabi. 
It's the recent reference I added to the Zabi family page about the Autonomous Republic of Munzo becoming the Autonomous Republic of Zeon and the practices it undertook before it became the Principality in 0078. So I'm afraid some side materials are no longer completely reliable. Pity, I would've preferred if the Principality was founded the date it says on the page here.
