Sivar, Vega Sector, circa 2654.

The Sivar dreadnaught was the Empire of Kilrah's primary battleship of the line for the first two decades of the war. Some 700 were identified by the Confederation during this period. All eight noble clans build Sivar-class ships, although the Kiranka took over production during the consolidation of power which began in the 2650s.

The Sivar has an exceptional engine capacity which makes it the fastest battleship on either side of the conflict. Sivar are used to quickly using men and fighters to trouble spots. Unlike their larger cousins, the Snakeir super-dreadnaughts, the Snakeir is focused almost exclusively on ship-to-ship action: their torpedoes are targeted antiship versions and their warrior complements are trained for starfighter and boarding operations.

The Sivar differs from the ship which destroyed the Goddard Colony; confusingly, this prototype weapon was assigned the codename SIVAR by the Confederation. Several Sivars were captured by the Confederation, including an unarmed example during the Epsilon Initiative which was taken in drydock.
