Like Kitana and Rain, Tanya is an Edenian, a native of a realm konquered by Shao Kahn and merged with Outworld millennia ago. The Edenians have been fighting for independence ever since. Though she's a skilled kombatant, Tanya prefers more subtle means of achieving her goals. Most recently she and Rain have allied with the ousted former Outworld empress, Mileena. Tanya and Rain will help Mileena regain her throne in exchange for the creation of a new Edenia. What will become of Tanya's relationship with Mileena thereafter, none can say...
With Mileena executed, Tanya's dreams of a free Edenia seemed dead as well. She and the other rebels were fugitives from Kotal Kahn's justice.
Her fellow Edenian Rain had proved a powerful ally and a satisfactory konsort. But he had become useless to her.
In exchange for leniency, Tanya informed the Kahn of Rain's whereabouts. Imprisoned but alive, Tanya's plotting began anew.
