Well to be blunt, D'Hara rather chose to create this waste of time when they declared war and overrode peace talks. Aurvandil didn't want to waste our time faffing around with D'Hara and Terran.
I assume you are talking about D'hara declaring war on Provencia, then D'harans saw that as an insult because we were firm on keeping Paisly, I believe you said something like, if you guys remain neutral, sure. Then we remained neutral, Aurvandil made Provencia in Paisly. We were pissed but dealt with it, but Machievel went and attempted a religious uprising, got arrested, and we were just like, ok I guess, then Machievel told us he was tortured and we got pissed enough to remain neutral. So were we trying to workaround the neutrality? Yeah, but torture of our most respected noble and longest standing one was not needed.
