For the record, you have absolutely no idea what you're talking about regarding D'haran attitudes because you saw it from Aurvandil's side which obviously was not involved in the internal affairs of D'hara and Terran, Noblesse.
Rynn and D'hara completely went neutral for a significant portion of time, giving absolutely no aid to allied forces, which caused great strife between Alura and Rynn, and nearly ruined their relationship. Pissed us the hell off, it did. I was ready to write off D'hara at one point. Rynn was very hopeful and dedicated to stay neutral and I very pointedly remember the inconsistencies in Mendicant's actions and words being the cause of strife. Not to mention the supposed Lurian supporters who were working for Mendicant behind the scenes, though that's all speculation and pointless. Hell, Alura has contacts in every nation on the continent, that doesn't mean their entire nations are allies or even friendly with Alura (or Terran for that matter), it just means she has a lot of friends. So, on that token, the Lurian thing is just hearsay and can't really be used against Mendy, sadly. Anyway, the point is, Rynn and D'hara in fact WERE neutral, and as much as I tried I couldn't convince them to do otherwise. If it weren't for certain events and things said by Mendicant, the neutrality would have continued. The Provincia thing though was the final !@#$-you. Even with the neutrality ended, D'hara was still not going to re-join the war until that little insult came to be. It completely changed our plans and really brought the entire coalition together, so thank you for giving Rynn an excuse to marry Alura sooner than planned and bring the armies of D'hara to Paisly.
Also, for the record, Barca is horrible at communicating. Despite being a Marshal and then Ruler, I heard absolutely nothing about peace talks, and when it was finally mentioned (and far too late, might I add!), absolutely no details were given. Peace talks should ALWAYS be occurring - that doesn't mean anything's actually happening. Unless we heard from Barca that there was progress in the peace talks and they asked us to back off, it might as well be another empty Gaza Strip trick. Quite the contrary, Barca ran to us and asked us to get involved so we did, and then bailed on us. I literally sent messages to multiple Barcan nobles who, as Aurvandil was closing in, DECIDED TO LEAVE THE REGION. Who the hell LEAVES the gathered armies of the allied forces defending YOUR territory right as the enemy arrives? And not one of them ever bothered to reply to my messages. I have to admit, that was the most ridiculous thing I've ever seen in over a decade playing strategy-war games online. Then, Barca's General went MIA, no one would reply to our damn messages, and we figured Barca had collapsed from within. Next thing I know there's Zuma around and they're coming back to life, and I just scratched my head and wondered what the hell happened in the time they were silent. Barca's leader is actually sort of communicating in the Moot now, once in a blue moon, which is literally the most I've ever heard from Barca in the time I've been playing. I really want to trust and believe in Barca but they've not shown me much reason to. Hell, I've more faith in Asylon's ability to remain (in-)consistent right now than I do in Barca, and that's just sad.
A lot of things could have gone differently... A lot of things.
