We all know the details of this by now, and everyone has their IC reasons for perpetuating the war, but let's be clear about WHY Luria suddenly went from war with Aurvandil to war with D'Hara. D'Hara seriously entertained the notion of either coming to the aid of Fissoa in its war with LN or allowing Aurvandil to pass through so THEY could come to the aid of Fissoa, solely in a pragmatic attempt to deal with a potential threat before it had emerged. That is why Luria went to war with D'Hara. They were the proximate threat.
Honestly, I have never heard any of these suggestions before as a member of D'hara but I had little political power at the time to be informed of plans though too. The thing that gets me is you are buddy buddy with Fissoa but since we considered helping an ally, we are the bad guys, not the ally.
