Shockingly, Siri abandoned the Jedi order shortly after the Battle of Naboo. While tracking smugglers on the Kessel Run, Adi Gallia and Siri engaged in a severe disagreement which culminated in the younger Jedi's departure.
Siri not only turned her back on her training and heritage, but she allied herself with Krayn, one of the most despicable
slave traders stalking the Republic spacelanes.
(My own little bit since SW.com didnt finish her Profile so they didnt spoil Jedi Quest for people.)
She was later encountered again by Obi-Wan Kenobi and his Padawan Anakin Skywalker, she captured Anakin but
hid the fact he was Jedi from Krayn.
In the end Obi-Wan figured out something was amis and confronted the Jedi Council, they admitted Siri was
on a deep-cover mission and had been since she left the order.
Later, Siri was revealed to be a Jedi and with the help off Anakin and Obi-Wan, Krayn was stopped, though
not arested as planned.
Anakin had killed him.
Siri is now once again among the ranks of the Jedi Order.
