Ok, new nation idea. Alchemical scientists studying bizarre phenomenon figured out that the universe isnt purely made of matter, but another kind of matter interacts weakly with physical matter and allows the creation of alloys and stuff, this other matter is usually pretty much invisible and tends to be alive, some of it is sapient. The sapient "othermatter" beings can under certain conditions interact with human neurochemistry allowing them to communicate with the people of the nations if they drink special potions created by the alchemists/

There are two problems with this, though. First being this flowerly and needlessly complicated explanation makes it kinda ridiculously advanced. Second, what the hell this thing is even good for? You didn't specify anything which makes it hard to judge.
