Jax Pavan 17 was one of the 582,797,754 Human males named Jax Pavan on Coruscant. After being denied an alcoholic beverage at the tender age of 17, he tinkered with forging identification that would pass muster at the local liquor store. What young Jax came up with turned out to be so good, that when he was drafted into the Imperial Army, he used his fake ID to make the authorities think he was not physically qualified to serve in the military. After that, he began a long and prosperous career as a document forger, at first working for the Coruscanti underground movement Whiplash, then the fledgling Rebel Alliance as it began to send agents to the capital world.
Eventually, Jax was recruited by New Republic Intelligence, crafting impeccable credentials for use by agents infiltrating other worlds. Some of his handiwork would be used by such units as Rouge Squadron and its sister unit, Wraith Squadron. Pavan also worked at cracking Imperial Intelligence forgeries, where he succeeded in wigging out as many as seventeen Imperial spies.
