In Michael Stackpole’s “I, Jedi” it is said that the father of Mirax (Boomer) has a Imperial Star destroyer painted red. Michael does not to my knowledge mention where Boomer who is not an Imperial character got his Star Destroyer. Do you know if any other author mentions where Boomer found/stole/received this unusual gift? — Scribe
The Errant Venture, Booster Terrik’s Imperial-Class Star Destroyer, first appears in The Bacta War by Michael A. Stackpole, book 4 in the X-Wing Series. Other canonical books that the ship is mentioned in are X-Wing: Isard’s Revenge (Stackpole), Specter of the Past (Zahn), Vision of the Future (Zahn), and Star Wars: Union (Stackpole).
Originally the ship was Virulence and it was naturally in Imperial service. Under the command of Joak Drysso during the Battle of Endor, it was present at the destruction of the Executor and the defeat of the Imperial forces. Drysso joined forces with Ysanne Isard, who later promoted him to command her battleship and left the Virulence under the command of Lakwii Varrscha. During the eponymous Bacta War, Booster captured the Star Destroyer, took command, and put his own people on board; later he was able to turn the tide of the fight to Republic victory with the Star Destroyer. Afterward, despite the reservations of New Republic command, he kept the ship. The deal secured by Corran Horn and Airen Cracken was that the Destroyer could remain in Booster’s control after it was stripped of most of its weaponry (these were sold, earning Booster 18 million credits). Renaming it the Errant Venture, Booster had it painted red and transformed it into a base of operations and kind of mobile bazaar with its own reputation.
