It is unknown which system Gloom came from, but it was believed that he grew up in the bowls of Coruscant's rough streets. He made a living peddling death sticks in Coruscant's entertainment districts working for crimelords as they came and went until he was captured by Jango Fett. Fett interrogated Gloom for information on the Bando Gora, information that would lead Jango to Groff Haugg and eventually to corrupt Senator Connus Trell.
