As far as Faq goes, it's gonna be Transylvito, likely on the very next turn. Which is great for them, as they lose the least (~3 warlords) and gain the most (3 cities) of all combatants... other than GK, depending on how many units of what quality they decrypted.
Balder has already said Jillian is going to meet Don King, so... if she did try to gank her cities (why?), she would soon lose them.
And there wouldn't be any money in the ruined cities... when you beat a city, you take its treasury. That's hard-wired. Now, if they had been left at level 1, and their Ruler & heir(s?) killed, they would be frozen in time and the money would still be there.
