Saskia was a high school student on the Outer Colony of Meridian when the moon came under attack by the Covenant in 2548. Together with three other students and a SPARTAN-III, she was able to evacuate the population of her village from the planet.
Saskia was the only child of two wealthy arms dealers, who engaged in war profiteering, selling to both the UNSC and Insurrectionist groups. In her youth, she attended a UNSC prep school, however in the late 2540s her parents moved to Brume-sur-Mer on Meridian, and she transferred to a local high school there.
In 2548, Saskia's parents left the planet at short notice, and shortly after the Covenant laid siege to Meridian. Saskia lived outside of the village of Brume-sur-Mer, and so was unable to enter the local shelter. Instead, she took refuge in her parents' home, which was equipped with prototype defensive systems. From here, Saskia rescued fellow students Evelyn Rousseau, and Victor Gallardo from a Kig-Yar soldier; shortly after, Dorian Nguyen joined their group.
The four students joined up without a wounded SPARTAN, Owen-B096, and were able to rescue the population of Brume-sur-Mer from the shelter - which was starting to flood due to inclement weather - and evacuate them from the planet in an old Insurrectionist Prowler. Saskia personally lead the refugees out of the shelter and to the ship. She was awarded the Medal of Honor for her part in the events.
After being exposed to Forerunner artifacts on Meridian, Victor developed a genetic anomaly that prevented his injuries from being healed, something that his friends were also discovered to have. However, Owen-B096 proved to be immune due to the genetic modifications from his Spartan-III augmentations. With the permission of Victor's parents, ONI began the process of augmenting Victor into a Spartan-IV supersoldier in hopes that the genetic modifications he would receive would cure Victor's condition. The attempt appeared to be working and ONI offered Victor's friends the same option. After considering the idea, the rest of the group agreed to become Spartans, knowing that if Victor had been given the choice instead of his parents making it for him, he would've agreed to undergo the procedure.
