Zoner's fight back.
If the QCB want to do this then they can't complain if they end up being hunted mercilessly throughout Sirius by Zoners and their friends.
Honestly, Zoners are powerful. They just need some leadership behind them. I fear with Mal gone that may have been taken down a step.
Zoner's are powerful, they need to be caught between two strong powers in a constant war, but attacking a House? I'd rather see them wage a war on the QCP while forcing diplomatic pressure on the Bretonia Government to take these rebel QCP (*cough's loudly) into account!
For Zoner's to actually declare war on a House they may find a certain ally of Bretonia taking an interest... (Just a potential RP idea there)
