In the year 132 BBY, a secret Sith assassin named Mae Aniseya, along with her associate Qimir, found themselves in conflict with members of the esteemed Jedi Order on the planet Olega. Aniseya infiltrated the Olega Jedi temple with the intention to kill Jedi Master Torbin, but her attempt was unsuccessful. This failure exposed her whereabouts to a group of Jedi led by Jedi Master Sol, who were actively investigating her murder of Jedi Master Indara. Despite this initial encounter, Aniseya managed to breach the temple once more, confronting Master Torbin. Torbin then took his own life using Bunta poison that Aniseya had provided. The Jedi, recognizing the recent concoction of the poison, traced it back to Aniseya's accomplice, Qimir, who had assumed control of the local apothecary.
By utilizing Aniseya's twin sister, Osha Aniseya, to impersonate Mae, the Jedi extracted information from Qimir. He confessed to supplying the poison and revealed that Mae was under the guidance of a master. Subsequently, the Jedi confronted Qimir directly, obtaining intelligence that enabled them to set a trap for Mae. Qimir further disclosed that Mae's mission was to assassinate four Jedi: Indara, Torbin, Sol, and the Wookiee Jedi Master Kelnacca. When Sol finally cornered Mae, they engaged in a hand-to-hand combat duel, during which Sol relieved Mae of her knives. Sol, along with his team member Jedi Knight Yord Fandar, then revealed to Mae that her sister was still alive. Meanwhile, Sol's Padawan Jecki Lon provided aerial support using a Polan-717 Jedi transport. With no weapons and nowhere to turn, Mae escaped by creating a large dust cloud. Osha then attempted to prevent her sister's escape, but her efforts were in vain.
