For ME, if you're arrowaine's vassals, after all we and FCC have done for you, that makes it straightforward. I sincerely hope your post is ironic, but I fear it is true. Sanders, ALL of the fiefs you used to own were seized or sold by my vassals. Make your choice smartly. If you choose occitan overlordship, it is what it is. I sincerely implore you to reconsider. You are on the border of a great war, LCO is not the NA choice. At the worst, independece until the last remains to you, but attacking FCC in accordance with LCO wishes would make you a tool. Remember the where you have come from, LCO had NO PART.
Edit: you are Raven vassals to the extent you allow yourselves to be
Yes, I was being silly and facetious. Pretty much everything I put in spoilers is meant to be taken as a joke. We do not make decisions at anyone's behest. If a decision is made that happens to be in accordance with another's, it is by coincidence. However, to avoid communication and cooperation with someone who is an enemy of your enemy would be foolish. It has been made clear that we are determined to make war upon FCC. If LCO were to abandon that front and whole-heartedly attack someone else, we would continue to fight FCC. We'll fight them until something drastically changes or we no longer have the ability or zeal to do so.
I also recognize that we have received our core fiefs from others, namely you and FCC. However, I feel that we have paid that debt by cooperating heavily through mercenary support, logistic and military support (in FCC's case) and intel on Occitan troop movements (in TkoV's case). I do not see the problem with the seizing of Elherdah and Yalibe. We would not have touched them if Bonesaw (who represented HoC, regardless of whether his decisions were sound) had not declared war upon us and Ravens without significant provocation. We felt that the seizure of a couple HoC fiefs were justified. I do understand that Bonesaw made a rash and foolish decision (according to him it would likely be perfectly fine since he was quitting strategus altogether), but to me, that does not justify the unconditional return of former VE fiefs when they were held by HoC at the time.
If you have anything to discuss, I would recommend that you contact me directly! Ravens are close friends of ours, it is no secret. However, they do not call our shots and they do not represent us. Perhaps that was not the case when Fimbulvetr was an entity, but those days are over. We are likely to support Ravens as they are likely to support us; but we are not firmly obligated to do so, at least not as I see it.
