Biography
Isabel was created in March 2556 by scanning and replicating the neural pathways of Anarosa Carmelo, a test pilot who was killed in an accident. Isabel did not begin her first assignment until early 2558, however, having first been relocated to Earth for training. When that was completed, she was tasked with managing logistics at the Henry Lamb Research Outpost on the Forerunner Installation 00, where she was in charge of food supplies, life systems, and power management. At some point, the portal from the Ark to Earth shut down without warning. A month later the Henry Lamb Research Outpost was attacked by the Banished, led by Atriox. Though Isabel witnessed the deaths of the outpost's personnel, she survived the attack and remained hidden from the Banished.

Isabel issued a distress beacon which was later encountered by, which had arrived over the Ark through unknown means in 2559. Spartan Red Team was deployed to the Ark to investigate the beacon, where they came across Isabel. They extracted her from the outpost and took her with them back to Spirit of Fire, where she informed Captain James Cutter and his crew about the state of the galaxy. While she initially urged Captain Cutter and his crew to flee the Banished, Isabel was ultimately convinced to stand along alongside them and fight Atriox's forces on the Ark. Now stationed aboard the Spirit of Fire, Isabel used her logistical background to make many improvements to the ship's security and safety protocols, as well as to its various systems.

Isabel considered the research team at the outpost she managed to be her friends and was greatly distraught when they were killed by the Banished in a surprise attack. Having no combat experience, she became afraid and sought to escape the facility. She would come to hold a grudge against the chief of the Banished, Atriox. Isabel agreed to help the crew of defeat the Banished, as she fought for retribution and desired to find a new family among the ship's crew.
