Overview
Isabel was created for logistics management on the heavily damaged Installation 00. Her base was later destroyed by Atriox by surprise, killing all of her friends, causing Isabel to swear revenge against him. She was later saved by James Cutter and his SPARTANs, and integrated herself into the UNSC Spirit of Fire, which allowed her to inform the ship's crew of what happened during their twenty-eight years in cryosleep.
