Garthus Hal, a Human, made his living as a mercenary specializing in explosives and bombing operations.
His formative years saw him cycle through roles as a soldier, a pirate, and a gambler, but his talent for demolitions quickly brought him renown. Having built his reputation, he launched a freelance bombing enterprise with a small group of associates he referred to as "lads." Garthus, devoid of moral constraints, offered his services indiscriminately to the Galactic Empire, the Rebel Alliance, and a variety of terrorist organizations, always siding with the highest bidder. He gained notoriety while employed by Moff Jander Graffe, who tasked him with orchestrating terrorist attacks on the world of Esseles while falsely attributing them to the Rebellion. One such attack, a bombing at the Togatto Speedway, resulted in the deaths of numerous well-known racers.
