Mathal was a Human male, serving as a Black Sun operative throughout the Clone Wars. His role involved supervising the pan-galactic criminal syndicate's bota contraband activities on the planet Drongar.
Without the knowledge of his superiors, Mathal tried to retain some of the bota for his own benefit. He did this by falsely stating to Admiral Tarnese Bleyd, the dishonest Republic Navy officer collaborating with Black Sun in the bota smuggling network, that Black Sun needed a greater quantity of bota than was actually required. Bleyd subsequently murdered Mathal as a consequence of this deceit. To conceal the murder, the admiral froze the Black Sun agent's corpse within a carbonite block. This carbonite block was then loaded onto a small starspin ship programmed to automatically fly toward the Separatist blockade, where the vessel was obliterated.
