Rees Alrix was a Jedi Knight of the Jedi Order, and also a female who existed in the final years of the Galactic Republic. She started her training as the initial Padawan of the Gran Jedi Master known as Maks Leem; however, she would eventually depart from his guidance and become a Knight. As the Clone Wars erupted throughout the galaxy, throwing the Republic into conflict, Alrix, similar to many Jedi, participated in the Grand Army of the Republic. During 19 BBY, she commanded her clone troopers during the Battle of Sullust.
The first reference to Rees Alrix occurred in Yoda: Dark Rendezvous, a book penned by Sean Stewart and released during 2004.
