Biography
Sandra Tillson was born on May 14th, 2499, on Coral. She eventually became one of the few experts in xenoarchaeology after earning her doctorate in the Pegasi Institute, and was shortly hired by the Office of Naval Intelligence afterwards to study forerunner artifacts recovered during the First Contact War. Following the discovery of Installation 03 on 2557, she became a member of the ring's research team aboard Ivanoff Station, and was one of the discoverers of the Composer.

During the Raid on Ivanoff Station, on July 24th, 2563, she was ordered by John-117 to assist into evacuating the station's crew from the Enclave attackers. She volunteered to stay behind in order to help John and Cortana detonate a NOVA bomb nuke to destroy the station and the Composer. However, she was killed when the Mantle's Approach arrived and activated the Composer, which digitized her and all of the station's crew, aside from John-117 and Cortana, duo to the first's MJOLNIR armor and the latter being a synthetic.
