White Nova was a Harrower-class dreadnought that the Sith Empire utilized during both the subsequent Galactic War and the preceding Cold War. Functioning as the flagship for an Imperial fleet, it orchestrated an attack against the Republic Thranta-class corvette named Dorin's Sky, and later against the Foundry, which involved breaching the Republic blockade protecting it.
BioWare's video game, Star Wars: The Old Republic, which was released on December 20, 2011, marked the initial appearance of the White Nova. Imperial players can use it as the starting point for flashpoints and operations.
