The Darkvenge functioned as a Lucrehulk-class battleship for the Trade Federation, helmed by Vicelord Siv Kav.
This vessel served as the flagship for Special Task Force One, belonging to Darth Sidious', who planned to annihilate Outbound Flight in 27 BBY. Nevertheless, Force Commander Mitth'raw'nuruodo (whose core name was "Thrawn") of the Chiss Expansionary Fleet launched an assault that led to the destruction of Sidious' entire Task Force, sparing only the Darkvenge.
A ship that would become known as the Darkvenge was initially referenced, though without a name, within Timothy Zahn's 1998 book, Vision of the Future. Its initial appearance, along with its official name, occurred in Zahn's 2006 novel, Outbound Flight.
