Then fonons serve a similar purpose on my world. Depending on your world, you may or may not have a "periodic table", where elements are neatly categorized and numbered, but when I tell you that each fonon has an element on my world I mean something rather different: there are seven elements, and combinations of these make up all matter.
[ rattling, rattling ] Darkness, Earth, Wind, Water, Fire, and Light are the first six; fairly standard concepts, if nothing else, but the seventh known fonon is classified in a more unorthodox manner. "Sound", we've called it since its rediscovery; it's also related to memory, and use of it grants one the ability to heal.
[ a beat, and then he adds smoothly ] Ah, yes; and that is another thing. On my world, it is possible to manipulate fonons through the fon slots on one's own body; those with the talent for it are called fonists. Through this manipulation, a version of "magic" is achieved.
[ of course, in the future, that is going to continue to become more and more difficult, but alas. ]
