i would use subject of the thread to pose one more question - is it a bug if the realm whom we hate can begin friendly takeover against us (seen on dwilight)?!
Similarly, Port Nebel has just revolted to Corsanctum again. However, last I checked, they hated that realm more than anything in the world. Well, them and a few others.
Corsanctum did not perform a friendly takeover. We would have to be at war with them if that were the case.
Now, we could have a diplomat-ninja working for them, raising sympathy of Corsanctum...I think we've just discovered the new infiltrator! Meet the diplomat, able to fling gold-coins like throwing knives, with mind-control abilities undetectable by other nobles!
However, none of the nobles of D'Hara in-region are diplomats. Pierre von Genf, Marquis of Caiyun, Ambassador of Morek Empire, now he could be causing trouble...
