Yes. Yes, she was.
Liar, liar, pants on fire.
Since this is an OOC forum, and not the Indirik family's personal IC propaganda machine, I'll just go ahead and confirm, OOCly, that CE had NO plans to attack Carelia. CE is not so arrogant to plan for a two front war, and its target was the northern realms. CE was already mobilizing against Eston before Talerium declared war on Eston, when Carelia stabbed CE in the back.
If anything, CE was hoping that Carelia and Caergoth-Suville would stop fighting, so that the entire south would unite and finally crush the uppity northerners. CE was saber-rattling at Caergoth-Suville to try to pressure them to sign a peace deal with Carelia, because its leaders were worried that Carelia seemed to be losing. Yes, CE was playing the part of a bully, but it was a bully
on behalf of Carelia. Those in the know in Caergoth and Suville can confirm this.
So, yeah, CE left itself right open on the diplomatic front, exerting pressure on Caergoth-Suville right when the northern realms were painting CE as a bully, and Carelia was promising two duchies to Caergoth-Suville in exchange for ripping two duchies out of CE. CE was trying to help exactly the realm that was trying hardest to destroy it.
That's why there was so much outrage when Carelia jumped on the anti-CE bandwagon. There was definitely a sense of betrayal there.
CE's nobles hated Magna Serpaensism due to their experiences fighting Falasan, but there was an uneasy ceasefire after they fled to Carelia. I'd like to note that CE did not do anything while more and more Serpaensist lords were appointed in Carelia, but you can bet that CE was keeping tabs on you. Nathan just threw a torch into the tinder-box that is anti-MS sentiment.
