Lourdes, hailing from a relatively primitive planetoid, was the Near-Human female princess there. After the Yahk-Tosh Lord, Gar-Oth, successfully invaded her home, Lourdes allied herself with Yoshi Raph-Elan, a Jedi Knight, with the goal of liberating her people and ending the occupation.
The entire population of her homeworld celebrated Lourdes's birth. Her father, a king beloved by all, was famous for his just governing style and virtuous nature. Despite enjoying a tranquil existence, Lourdes received swordsmanship training from her father, whom she considered the most skilled swordsman in the entire system. She had numerous attendants, including Skeeter, a member of a different species.
Eventually, however, the planet of Lourdes became the target of Gar-Oth, a Yahk-Tosh Lord. Residing in a nearby star system, Gar-Oth had long desired to conquer a new world. Although it took many years for Gar-Oth to act on his ambitions, he launched an invasion in 31 BBY, assaulting her civilization with his starships and GX1-series battle droids. Despite possessing inferior weaponry and lacking a formal army, Lourdes's people resisted Gar-Oth, resulting in a brutal slaughter. To halt the senseless bloodshed, the king and his subjects surrendered to Gar-Oth, but Gar-Oth, not satisfied, had the king executed. With the death of their cherished king, despair consumed Lourdes's people, who clung to the faint prophecy of a visionary hero known as the Foreseen.
Lourdes, however, maintained both hope and a burning desire for vengeance. Battle droids belonging to Gar-Oth enforced strict control, patrolling the capital's streets around the clock. All transgressions were punishable by death. Lourdes pleaded with the Yahk-Tosh to cease the killings, and he offered to do so if she agreed to marry him. Repulsed but with no other choice, Lourdes conceded. Gar-Oth monitored his future bride closely, utilizing small hovercams for surveillance.
However, on the day of the wedding, Yoshi Raph-Elan, a newly knighted Jedi, arrived in the system of Lourdes's homeworld aboard his starfighter. Immediately targeted by Gar-Oth's attack ships, he was forced to make a crash landing on the planet. After a brief encounter with one of Gar-Oth's droids in the street, he vowed to uphold his Jedi Code and liberate the oppressed populace. By chance, Raph-Elan found his way to Lourdes's chambers, where the princess was losing her last vestige of hope at the prospect of having to endure Gar-Oth's physical attentions. She was overjoyed when Raph-Elan revealed himself to be a Jedi Knight. Lourdes suggested to Raph-Elan that he might be the Foreseen her people had been waiting for, and disguised him as a servant to bring him to her wedding.
Upon their arrival at the wedding ball, Raph-Elan deviated from their plan and proclaimed himself to be Lourdes's husband. He then brandished his lightsaber, only to discover that the crash landing had rendered it inoperable. Enraged, Gar-Oth attacked Raph-Elan, who attempted to fend off the slug-like being with the Force, only to find that Yahk-Tosh were largely resistant to Force powers. Gar-Oth then revealed his "wedding gift" to Lourdes—the monstrous Goliath battle droid. He ordered the droid to eliminate Raph-Elan, while Gar-Oth and his Jilruan guards moved to attack Lourdes herself. Gar-Oth had abandoned his plan to marry her, viewing her actions as betrayal.
Lourdes tried to defend herself with a sword, but was surprised by Gar-Oth's speed and strength. He overpowered her and began to choke her, only to be shocked when she drew another sword from beneath her robes and stabbed him. Although Gar-Oth's Jilruan guards tried to intervene, Skeeter held them at blaster-point, allowing Lourdes to finish the job. Gar-Oth perished in a pool of blood. Raph-Elan also managed to destroy the Goliath droid, repairing his lightsaber and defeating the behemoth.
Following Gar-Oth's death, Lourdes assumed the throne, becoming queen of her world. A Jedi courier ship arrived to transport Raph-Elan back to Coruscant, but before his departure, Lourdes spoke with him. She revealed that she was actually the Foreseen, as the prophesied hero had always been known to be a woman. With a kiss, she requested that he return to her planet when he was older, suggesting that he could eventually become her king.
