An elderly career soldier and a friend of EmperorPalpatine, Vanko was one of two Moffs with territories bordering the Maelstrom. Along with Moff Torpin, Vanko submitted falsified budgets and financial reports to the Empire to try and disguise the fact that he was losing a great deal of money to a pirate group called the Riders of the Maelstrom. He and Torpin met in secret on the planet Aris, then boarded the Kuari Princess to discuss what their next moves would be. Both believed that the pirate groups were working with the Rebel Alliance to plan a major offensive against their forces. Vanko and Torpin barely escaped from the Princess after it was hijacked by the Riders and rescued by Alliance agents.
