My research (such as it was) yielded similar results. I saw only that Piltogg used them during the QoP, they are mentioned as a chief export in the Vesuvius article, and as a military objective in the Silvarian Empire article on the old wiki. Silver told me that they were a power source of some kind and that they were a reference to that anime (which I have never seen). Wiki search reveals that is a mineral used as a superconductor and is responsible for much of the advanced tech in that universe. Quick glance through the article also tells me that we borrow a shitload of ideas from that show, jesus.
I don't really see how we can twist it to BrikWars purposes, though. What makes it different from other fuels? That is, what makes it brikwarsy as a fuel?
