Kira was formerly the Intendant of the Alliance space station Terok Nor, with her second in command Elim Garak. Kira ruled over the station with an iron fist, but used varying methods to do her job. She was manipulative where necessary, but ruthless and violent on other occasions, often rounding up Terran slaves and executing them randomly. She did, however, often view certain people with a certain affection, allowing them privileges in return for their loyalty and dedication. When Major Kira Nerys crossed through the Bajoran wormhole into her universe in 2370, the Intendant became enamoured with her counterpart.
Kira often displayed hedonistic tendencies, surrounding herself in her quarters with human slaves both male and female. By 2375 she had also, apparently, engaged in a relationship with Ezri Tigan.
She was particularly fond of Benjamin Sisko. She allowed him to have a ship and a crew, which he used to commit acts of piracy in order to collect tribute for her. She was horrified when Sisko turned against her and formed the Terran Rebellion. When he returned to the station to rescue Jennifer Sisko, Sisko used this fondness to manipulate Kira into allowing him to see her.
Kira was captured by the rebels in 2372 and tortured for information, but escaped after having manipulated Nog into helping her escape, killing him shortly afterwards.
In 2374 Kira and Bareil Antos crossed over from their universe in order to steal a Bajoran orb. She was prevented from doing so by Major Kira Nerys.
By 2375 Kira's failure to stop the rebels resulted in her being forced to bargain for her life. When Zek made the mistake of visiting Kira's universe to open trade negotiations, he was quickly captured. Kira arranged for Ezri Tigan to force Quark and Rom to deliver a cloaking device. After Rom sabotaged the cloak, leaving the ship defenseless against the ISS Defiant, Kira was able to escape.
