"Ah.
Vanda Nossëo was founded in the aftermath of a particularly destructive war on a now-member world called Elentári, which was ended by the acquisition under desperate circumstances of fairly unfathomable amounts of magic power. The founding nation decided that they wanted to do humanitarian work as many places as they could and that an organization with membership requirements and carefully specified circumstances under which they'd bother non-members was a good way to have unfathomable magic power without being very scary. The founding nation was Elven. Elves are, um. Amentans come in Voa and also in - what's the place that shot down our diplomats and tried to hold them hostage -"
"Calado."
"Amentans come in Voa and Calado and many other formats. Elves are very low psychological variance, there are lots of planets of Elves at lots of technological stages and every single one hears about Vanda Nossëo and wants to divert a substantial part of the resources of their civilization to working on it. As a result - because we were the founding nation, and because we're a very uniform voting block and don't require any bribes to stick with the program because it's just, inherently, what we want to be doing - we have influence somewhat outsized to our numbers. We're also a monarchy."
"That's very unfashionable these days."
"Well, it's usually a bad idea. Arguably always a bad idea for mortal species. ...anyway two days ago our Prince Canafinwë Macalaurë decided he wanted to make proper contact with Amenta. Usually contact is just 'who's at the top of the list, give a briefing packet to a team with relevant skills' - and if this were like that, we'd have no hopes of convincing the budget office to give enough bribes to all billion people in Voa that the reds would favor membership without even actually getting any special perks out of it. But it's Prince Canafinwë and so possibly our resources are not all that limited after all...to be clear, he can make contact anywhere in the universe on a whim whatever the priority sheet says, but that doesn't imply he can get bored and drop it, once contact is made there are rules and we follow them."
