Crebbis was an Oxoorian male born on Oxoor in 53 BBY. He was captured by slavers in 46 BBY and sold to a Twi'lek merchant on Ghorganchu. For several years he worked for his master until he obtained his freedom in 31 BBY when a violent abolitionist group known as Festivities of Ryloth attacked Ghorganchu and freed hundreds of slaves. With few skills, Crebbis managed to become a bodyguard for a visiting Yarkora, Maeqush-Bont. It turned out that his employer was formerly a warlord on Erayyxa and had become a galactic wanderer. They traveled to many worlds and then in 27 BBY Maeqush-Bont decided he never actually needed a bodyguard and he left Crebbis with a small lump of credits on Metellos.
