A direct descendant of the Empress Teta. Aleema was heir, with her cousin, Satal Keto, to the throne of the Empress Teta System some 4,000 years before the Battle of Yavin. She was too rich, too spoiled, and too bored with life. First for amusement, then in a lust for power, Aleema turned to the dark-side illusions of the ancient Sith magicians.

She helped murder her aunt, uncle, and others, and staged a coup to take over the system as coleader of the Krath dark side cult. The spirit of the dark side Jedi Freedon Nadd bestowed upon Aleema certain dark side powers, including the ability to cast realistic illusions. Jedi Knight Ulic Qel-Droma traveled to the system in order to learn the Krath's dark side secrets, but he succumbed to the dark side himself and helped Aleema defeat her enemies. Later, Aleema attempted to reassert her power over Krath forces by abandoning Qel-Droma during an attack on Coruscant, but he was rescued and eventually had Aleema killed.
