RWBY World of Remnant Season 1 Episode 1 Dust Episode Title:Dust.Episode Description:The narrator explains Dust as four basic forms of a naturally occurring energy propellant, triggered by the Aura of humans and Faunus. It can be combined naturally or artificially to form stronger types, which Mankind harnessed for technology such as airships or androids. Only skilled and disciplined people can use its raw form without losing control, so the most common use of Dust is in ammunition - though some still use archaic means, like weaving it into clothing or their own body. While part of everyday life, humanity has no understanding of how it came to be - or how mankind's involvement with Dust will change Remnant.
