Li-Sun Jinn was created from Qui-Gon Jinn's Padawan braid at the behest of Darth Sidious to see if a clone of a Jedi would be Force sensitive. After a battery of tests by the Sith Lord, it was determined that the clone was not force sensitive. Count Dooku asked to keep the clone because he could be of use to the new Sith Lord. Dooku then used his new knowledge of Sith Alchemy to slow the clone's accelerated aging. Dooku then trained Li-Sun not as an apprentice but almost as a son. Dooku spared no expense at training Jinn, and even hired Jango Fett to train Jinn in many forms of combat.
