Fastblast was a cruiser of the pirate variety, a Invids vessel commanded by the rebellious Admiral Leonia Tavira. Those who served onboard the ship were known as the Fastblasters.
In 11 ABY, the pirate group called the Fastblasters became the initial target of Corran Horn, who was operating under the alias "Ghost Jedi". Horn's goal was to persuade the numerous pirates of Courkrus to sever ties with Tavira's Invids as part of his search for his wife. Following a severe beating inflicted upon three pirates—a male and female Human, and a Kubaz—Horn proclaimed that any Fastblasters he encountered henceforth would be killed. Three days later, the Fastblast departed from the system.
