As a Human female and a member of the Lost Tribe of Sith, Orlenda lived in the years after the Great Hyperspace War. She was an aide working for Seelah Korsin, the wife of the Lost Tribe's Grand Lord Yaru Korsin, in the sick wards managed by Korsin; the two women developed a close friendship. Around that time, Orlenda entered into a relationship with Gorem, a native Keshiri laborer, but this ended with his death due to a workplace incident.
In 4975 BBY, Orlenda found herself to be pregnant, and she stood by her friend Korsin as she plotted to remove her husband, Yaru, from power. While her condition prevented her from actively participating in Korsin's planned rebellion, which aimed to place her son, Jariad, on the throne, Orlenda's role was to ensure the continuation of Korsin's policy of Human purity within the Lost Tribe should the coup fail.
Orlenda, a Human female, was a member affiliated with the Lost Tribe of Sith, a Sith group that, after their ship crashed on the isolated planet Kesh in 5000 BBY, established dominance over the Keshiri natives of the world. In 4985 BBY, Kesh became Orlenda's home, and she served as an aide to Seelah Korsin, the wife of Lost Tribe Grand Lord Yaru Korsin and the leader of the group's sick wards. In this position, Orlenda assisted Korsin in her endeavors to guarantee the Human purity and genetic perfection of future Sith generations on Kesh, which involved gathering Human children and presenting them to Korsin for examination. It was around this time that Orlenda became romantically involved with Gorem, a Keshiri laborer. Sadly, her relationship with Gorem came to an end when he abruptly died while working at the crash site of the Omen, the ship responsible for bringing the Lost Tribe to Kesh. Grief-stricken by his passing, Orlenda attended Gorem's funeral and witnessed his body being cast over a cliff.
During that year, as part of their aspirations for Human purity, Orlenda accompanied Seelah Korsin to assess the genetic purity of the Human youngling Ebya T'dell, introducing the child to Korsin and offering general information about T'dell. Following an inspection of T'dell, and after voicing concerns about her appearance to Orlenda, Korsin turned down Orlenda's offer to examine other younglings on their list. Orlenda then informed her that the ward-room required a new Keshiri bearer, explaining the circumstances surrounding Gorem's death and his subsequent funeral.
By 4975 BBY, Orlenda had learned of Seelah's scheme to depose her husband, Yaru, and set the stage for her son, Jariad, to ascend to the position of Grand Lord. Already pregnant at the time, Orlenda was unable to actively participate in the coup, but she was selected by Korsin to ensure that her policies would be upheld even if her coup attempt failed. That year, just before Seelah planned to ambush Yaru, Orlenda was present with Jariad and a group of Sith Saber warriors near the Kesh Sith Temple located in the Takara Mountains. Although Korsin briefly entertained the idea of allowing Orlenda to remain by her side, she ultimately instructed her to descend the mountain with a cart filled with supplies destined for the capital city of Tahv. Despite Yaru's death in the resulting conflict, Seelah's plot was ultimately unsuccessful, and Yaru's daughter, Nida, inherited the throne.
Orlenda felt attraction toward Gorem, the Keshiri worker. She admired his physical strength and was saddened by his passing. Orlenda maintained a friendly relationship with Seelah Korsin, who viewed Orlenda as hedonistic and lusty and enjoyed teasing her about it. In 4975 BBY, Orlenda and Korsin were close enough for the aide to fully support Korsin's power grab, and she was willing to stand by Korsin's side during the battle. Orlenda possessed a slender figure and had straight, flaxen hair.
Orlenda utilized a piece of parchment to document details regarding Human children residing on Kesh.
Orlenda's initial appearance was in John Jackson Miller's 2010 eBook titled Lost Tribe of the Sith: Paragon, which served as the third installment in Miller's nine-part Lost Tribe of the Sith series.
