Rust

Rust is a corruptive contaminent found on many of the islets on Source. Kay discovers that it is not mineral matter, orgnaic matter or anti-matter. He determines that rust is flow, but with the flow molecules organised differently. When flow is used on rust the rust begins to dissolve or be absorbed by the flow. Rust causes many of the fauna inhabiting the islets of Source to become hostile, and they must be fought and pacified to clear them of the rust.
