Olivia-G291

Olivia is a Spartan III in Team Saber, one of the leading squads in the Gamma generation of Spartan IIIs. She is known the stealthiest. She Was the best sneak in Gamma Company. They called her "O" for short because she was as whisper-quiet as her vowel namesake. She is currently with the other survivors of the Battle of Onyx in the Micro Dyson Sphere Shield World.

Biography
Olivia was conscripted into the SPARTAN-III program, developed by James Ackerson around 2546 between the ages of 5 and 7 when she, along with other orphans volunteered to become Spartans and avenge her family and home planet. Once on Onyx, she and the other spartan candidates were trained by Senior Chief Petty Officer Mendez; surviving Beta Company SPARTAN-IIIs Lucy-B091 and Tom-B292; and SPARTAN-II, Lieutenant Commander Ambrose aka SPARTAN-051.

Olivia was assigned to Team Saber, under the command of Ash-G099. When Onyx came under attack by Sentinels, the teams were still vying for top honors. Team Saber went dangerously close to Zone 67 to avoid the other teams. The team spied what they assumed at the time to be a new kind of covenant drone because of the energy shields. They decided to investigate and the sentinels engaged. Olivia remained with the team as they tried to figure out the weak spots of the drones. She and the rest of the team hurled rocks at the drones and to their surprise, the drone's shields did not activate. The sentinel chased Ash into a hole and the rest of the team pummeled the drone with huge rocks, destroying it.

A general decision was made and the Team moved to the armory to get some real fire power. Team Saber met up with Kurt, Mendez, Tom and Lucy; and proceeded to play life and death games of cat and mouse with the sentinels. Olivia and the team met up with Kelly-087 and Dr. Catherine Halsey but had no time for pleasantries because they were soon engaged by a pair of sentinels. After that was over, the team took Dr. Halsey and Kelly to a bombed out bunker, while Olivia went out on watch. While in the bunker, Dr. Halsey revealed the origin of the Sentinels and what to do next.

Just as Team Saber was in the middle of battling the Sentinels, a covenant dropship from the Bloodied Spirit after it dropped out of Slipspace over Onyx; carrying the Blue Team of SPARTAN-104, SPARTAN-058, and SPARTAN-043; landed rather abruptly in the forest at the source of what was believed to be coordinates for a rendezvous point that was on the E-Band. It turns out that the signal was sent by Kurt and the other spartans. Olivia and the others were knee deep in sentinel trouble and decided to retreat back to zone 67 and regroup, with Blue Team.

By now, the team had figured out that the sentinels only come after them in pairs and there is always one overwatch, or observer that records all the action and reports back to the others, making the sentinels smarter and harder to defeat each time they engage in combat with the humans. So, the only what to turn the tables would be for the teams to take out all three of the sentinels. Olivia, Will and rest Team Saber, scouted out a tunnel to bury the sentinel pair in and Dante rigged it with explosives. They met up with Kurt in a tree and watched as Kelly gave the sentinel pair "the finger" and kept on running. She went through the tunnel and it blew up behind her, throwing her like a rag doll across the forest floor, but destroying the sentinel pair. Kurt dispatched Team Saber to go see if she was ok. Meanwhile, Tom and Lucy fired both rockets from their SPNKr rocket launchers and Linda timed her fire so the sniper rifle rounds would impact at the same time as the rockets. The ploy worked and that bought the team some time.

After the team destroys the two sentinels and the overwatch, they move to Zone 67. Once there, they discover the map room and the location of Team Katana. Olivia had picked up Katana squad's signal earlier. They'd reported they were being forced into Zone 67. Their signal was lost shortly thereafter. First, Dr. Halsey proposed that they go to the sentinel factory and make sure no more sentinels are made. Then, they move to team katana.

In looking in the map room and examining the Forerunner text, Dr. Halsey figured out how to utilize the Forerunners Slipspace Translocation System, similar to the one Cortana used on Installation 04. Just before the team was about to jump to team Katana, AI Endless Summer contacts Dr. Halsey and Kurt-051, telling them they need to destroy the Sentinel Production Facility in order to save Battlegroup Stalingrad. Halsey gets the teleportation grid working, and they all teleport to the Sentinel Production Facility near the northern pole in Onyx. Halsey sends them to destroy three key structures, which would bring the entire production to a halt. Using the teleportation grid, they go to the three structures and trick Sentinels into firing on them on a line with the structures. Having destroyed the structures, they teleport back.

Olivia and the rest of the team arrive at Team Katana’s holding area to find them in some sort of cryo-Slipspace containment cells. Dr. Halsey found out the meaning of the Shield World and also found out that the Covenant knew the location of the group and was on the way with an entire armada of troops to attempt to stop them.

Olivia, along with the other spartans made a loose half-circle kill zone around the entrance to the Shield World and picked off targets at range. They managed to defend the entrance to the shield, although, it had come at some serious losses. Will, Dante, and Holly had already perished. There was little time left and the covenant forces were closing in for the final kill. Kurt ordered Olivia and the rest of Team Saber thought the portal. Soon after, Dr. Halsey and the surviving Spartan-II's came through and lastly, Lucy came through with Tom over her shoulder, unconscious. The team waited Kurt's arrival, but he never came. Once the team was inside the Dyson Sphere, they made gravestones for William, Dante, Kurt and Holly. Now they had to find a way out of this Dyson Sphere.
