It's been a while so bear with me if there are any mistakes, and if you really want to delve into the holy grail of autism then you can read the old guide here https://rentry.org/chuubanite
It all starts with an imaginary particle known as vitubium which draws energy from the conceptual realm. Within the borders of a nation, you have a large gathering of people who all worship the same chuuba. This influences the vitubium in the area to be powered by concepts which align with that respective chuuba and her thread. Chuubanite is the name given to matter, usually a mineral, which is partially composed of vitubium particles in addition to its ordinary makeup. The energized vitubium in the chuubanite then gives the appearance of seemingly magical effects related to the relevant concept. For example, the concept of nature in /uuu/'s chuubanite powered the growth of their forests and the creatures dwelling within it. The full explanation of how it all works is like a blend of nuclear physics and quantum mechanics, but the tl;dr is that chuubanite are magic rocks we used as an overly autistic basis for Vitubia's magic system so we could add more fantastical elements to the setting.

If chuubanite does still exist in Viti then that's not the name people have been using for it for a while. Though with the way it was designed, chuubanite could still be the real explanation for how many things in Viti operate even if the locals don't know it or call it other things. That being said, not everyone likes using it as a mechanic, so don't feel pressured to include it if you don't want to. We are a lot less anal about keeping everything compliant with an overarching canon these days though.
