"In blackest day, in brightest night,
Beware your fears made into light.
Let those who try to stop what's right,
Burn like his power, Sinestro's might!"
"There is no wine as sweet as the taste of your enemy's worst fear."
Nifsara Aurelin hails from a world in Sector 3188 called A'kesh, where she claims to have been one of several concubines to her people's Empress. Almost immediately upon her arrival to the palace, she began establishing herself as the 'head' of the group -- brutally terrorizing both the servants and the other concubines. Soon even the Empress' male consort was in fear of this upstart and begged his lady to do away with her; claiming that Nifsara even planned to murder her and take her place. Bloodlines and 'royal' birthrights meant little to the A'keshen people, who instead favored a series of ancient trials of succession said to have been laid down by their gods eons ago. Nearly all of those who had won the right to rule had been female, thus leading to a predominantly female-lead society and it was through these trials that even the lowest born could become a ruler... if the last Empress' progeny did not pass them.
The Empress would never have the chance to make her decision, however, as Nifsara's taste for power and pain had drawn the attention of a yellow power ring. Infused with it's energies, she quickly turned it on her people and easily laid waste to her Empress and the majority of the palace guard. Having never seen such a power before, those who finally remained yielded to her rule and Nifsara abolished the ancient trials altogether to rule uncontested alone.
Unfortunately for her, accepting the ring also meant accepting her duty to Sinestro and the Corps. While a puppet council rules her world in her stead, Nifsara finds herself chafing under the dominion of Sinestro and would love nothing more than to usurp his command as she did her Empress'... but his command over the power of fear far exceeds her own and he shows no hesitation in putting her back in her place. So thus she bides her time... for now.
