The rachni prove to be hostile and begin a war with the rest of the galaxy. Negotiation with the rachni queens is impossible because they cannot be contacted in their underground nests on the toxic rachni worlds

### 80 CE

* The Rachni Wars continue. The salarians make first contact with and uplift the primitive krogan, manipulating them into acting as soldiers for the Citadel Council.

### 700 CE

* Krogan warlords leverage veterans of the Rachni Wars to annex territory from other races in Citadel space. Eventually the Council demands withdrawal from the asari colony of Lusia, but the krogan refuse. A preemptive strike is made on krogan infrastructures by the Spectres. The Krogan Rebellions begin

* The Leviathan of Dis, a genetically-engineered living starship believed to be nearly a billion years old, is discovered by a batarian survey team on the planet Jartar. The Leviathan disappears under dubious circumstances after a batarian dreadnought passes through the Dis system
