Jax Pavan was a common Corellian name. Circa 19 BBY it was the name of 582,797,754 Human males and an unknown number of females on Coruscant. The planet's Yaam Sector alone was home to 8,673 men who shared this name. This large number vexed Haninum Tyk Rhinann, when he was given the task of hunting down a surviving Jedi Knight named Jax Pavan.
This particular Jax Pavan was the son of Lorn Pavan. He worked as a private investigator, initially operating out of Yamm Sector's lower regions, also known as the Blackpit Slums, however he and his team were forced to relocate more than once due to the efforts of the Inquisitorius. The common nature of the name led the Jedi to not bother adopting an alias, despite the risk of making it marginally easier to track him down. He regarded this as a small act of defiance against the Empire, which had taken everything else from him during Order 66.
