maybye the Precursors were once enemies of the Kharaa and made Carar in the process. They bombarded the Kharaa with it, but proved useless and the Precursors were massacred and sought refuge on Planet 4546B, where they made the strain with green cysts, which was very deadly. Then the Sea dragon attacked the Disease Research Facility, unleashing Carar on the planet, killing 143 billion creatures in an extinction level event.
