The Moot is not funding either side preferentially. Well, okay, Barca is handing over a rich townsland again for no meaningful gain, but Madina's fine with that. They damn near approve. And sure, D'Hara is buying every spare bushel from Aurvandil and is extremely hesitant to pay Madina its higher price, but that's as much on Madina as it is on D'Hara, and if Madina isn't selling its food now, they might be forced to reconsider their price if they want to match Aurvandil on the field, or sea.
To state that the 'Moot favours one side or the other would be inane though. The Moot favours no one because they're the EU, not the US. Foreign policy can be determined as a group, but the only real agreement that's been reached in the Moot on this subject is to stay out of it. Not surprising when there are Duke's from D'Hara that favour Aurvandil, Duke's from Barca that favour Madina (if they're forced to favour either), other leaders in Barca that favour Aurvandil, and sensible leadership from Terran who want us to stay out of it as much as possible. Putting it this way, my character is likely the richest in Barca but the last place he'd send any gold is to Aurvandil. Chenier is likely the richest noble in D'Hara (or at least the most influential) but he's one of the biggest warmongers with a realm that was previously their largest supplier. Personally, I expect a bit of starvation in D'Hara will tame any thoughts of war that might be afoot and neutrality will rule. If they want to eat, at least.
I bring this up because, lets face it, as much as Hireshmont is the defacto leader of the Moot, he's really just the public face (obviously with a weighty voice) and the policies are determined by the individual realms. The individual realms won't act without the Federation, so little action of consequence takes place. Could there be funds being funnelled to Aurvandil by the Moot? Certainly. But I've not heard as much as a whisper about it and so if it is happening, its not from the Moot but from D'Hara. And frankly, I doubt it even then. Their "lets help Aurvandil" attitude seems recent enough to me. That doesn't mean they won't or haven't started in the last week or two. After all, fund Aurvandil to expand throughout Madina and your cheap food supplier has more food to supply your growing cities. D'Harans, that is a hint.
