Biography

Sandra Katherine Tillson was born on May 14, 2506, on Coral.[1] At some point in her life, Tillson studied and earned her doctorate in archaeology in the Pegasi Institute. She became one of only a handful of experts in the field of Xenoarchaeology, where she was then hired by the Office of Naval Intelligence to conduct research on a number of sites later deemed to be of Forerunner origin. When Installation 03 was initially discovered, she was one of the first people to be introduced to the research team. This led her to be the one responsible for the discovery of the Composer.[1]

During the Raid on Ivanoff Station in July 24, 2557, she assisted in evacuating the station, while Master Chief John-117 cleared the station of Covenant attackers. Tillson volunteered to stay behind to detonate the HAVOK nukes the Chief and Cortana planned to destroy the Composer with. However, she was killed when the Didact activated the Composer, digitizing her and everyone aboard Ivanoff Station save the Master Chief.[3]

Tillson's composed mind would be used for the artificial intelligence of TDS-009, a Promethean Knight in service to Jul 'Mdama and his Covenant.
