Volus Timeline

### 300 BCE

* A great volus exploration push begins, including the claiming of the Esori System.

### 292 BCE

#### July

* **8th** - Batarian/Volus First Contact occurs.

### 230 BCE

* The Citadel Council commissions the volus to draw up the Unified Banking Act, which establishes a standard galactic currency known as the credit and links all galactic economies.

### 229 BCE

* The asari discover the elcor home system and help the elcor locate and activate their nearest mass relay.

### 209 BCE

* First contact is made with the quarians.

### 1 CE

* The rachni, a species of highly intelligent hive-minded insects, are discovered when a Citadel expedition opens a dormant mass relay leading to their star systems. 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. The krogan prove able to survive the harsh environments of the rachni worlds and pursue the rachni into their nests, systematically eradicating queens and eggs.

### 300 CE

* The rachni are declared extinct. In gratitude for their aid during the Rachni Wars, the Council rewards the krogan a new homeworld. Free of the harsh environment of Tuchanka, the krogan population explodes.

### 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.

### 704 CE

* The Citadel Council makes first contact with the turians around this time and persuades them to aid in the war. After the krogan respond to the initial turian offensive by devastating turian colonies with weapons of mass destruction, the turians vow to stop the krogan from ever becoming a threat again.

### 858 CE

* The Krogan Rebellions end, though scattered krogan insurgent actions continue for decades. The turians fill the military and peacekeeping niche left by the decimated krogan.
* The Citadel Conventions are drawn up in the wake of the conflict.

### 2125 CE

#### June

* **3rd** - The yahg, an intelligent pre-spaceflight race, are discovered on the planet Parnack.

### 2157 CE

#### July

* The turians prepare for a full-scale war against humanity, but this draws the attention of the Citadel Council. The Council intervenes before hostilities escalate further, revealing the existence of the greater galactic community to humanity and brokering a peace between them and the turians.

### 2164 CE

* Ivor Johnstagg is sentenced to 21 years in prison for attempting to assassinate Venta Tox, the volus ambassador to the Citadel. Although Johnstagg claims to be acting on behalf of the radical human political party Eternal Earth, no connection is found and Johnstagg is diagnosed with paranoid schizophrenia. Backlash from the assassination attempt jeopardizes the Systems Alliance's bid for an embassy on the Citadel.
