Fontan Assembly was a lot of fun, even before the SoA question. I can't remember anymore though which rat betrayed our plan for the new realm though, was a bit too soon, leaving me to clean the mess mostly. And in Fontan, that was never easy, nothing was :-)
And Ryu's burden was a tough one and after the Oligarch incident, nobody really knows who to credit anymore hehe.
The rat if I remember rightly was Johhnn (sp?) who was a longstanding member of the high command and dumped several weeks' of letters in the Assembly revealing the SoA plan in detail.
