'''Dr. Sandra "Sandy" Katherine Tillson'''{{Ref/Site|Id=TMB|URL=https://www.halowaypoint.com/news/halo-the-machine-breaks|Site=Halo Waypoint|Page=Halo: The Machine Breaks|D=5|M=9|Y=2024}} ([[Service number|Civilian Consultant Number]]: CC-728304){{Ref/Reuse|VIS}} was an xenoarchaeologist in the employ of the [[Office of Naval Intelligence]]. In [[2557]], she was studying the [[Composer]] at [[Ivanoff Station]].{{Ref/Reuse|H4}}
==Biography==
===Early life and career===
Sandra Katherine Tillson was born on [[2506|May 14, 2506]], on [[Coral]].{{Ref/Reuse|VIS}} At some point in her life, Tillson studied and earned her doctorate in archaeology in the [[Pegasi Institute]], eventually becoming one of only a handful of experts in the field of Xenoarchaeology. During the [[Human-Covenant War]], Coral would be attacked, forcing Sandra to evacuate to [[Lodestone]]{{Ref/Reuse|TMB}}, 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]].{{Ref/Reuse|VIS}}

===Death===
During the [[Raid on Ivanoff Station]] in July 24, 2557, she assisted in evacuating the station, while [[John-117|Master Chief John-117]] cleared the station of [[Jul 'Mdama's Covenant faction|Covenant]] attackers. Tillson volunteered to stay behind to detonate the [[HAVOK tactical nuclear weapon|HAVOK nukes]] the Chief and Cortana planned to destroy the Composer with. However, she was killed when the [[Ur-Didact|Didact]] activated the Composer, digitizing her and everyone aboard Ivanoff Station save the Master Chief.{{Ref/Reuse|H4}}

===TDS-009===
Tillson's composed mind would be used for the artificial intelligence of '''TDS-009''', a [[Promethean Knight]] in service to [[Jul 'Mdama]] and his [[Jul 'Mdama's Covenant|Covenant]]. Following the [[Requiem Campaign]], TDS-009 would take part in the [[Battle of Oban]] as part of the [[Third Dignitary Schema]]. However, during their mission of assaulting a UNSC communications bunker and eliminating the humans within, TDS-009 encounters something that fills it with feelings of revulsion, dread and fear; a small humanoid devoid of facial features and wrapped in flesh that just stands staring at the Promethean Knight. TDS-009 attempts to wait for a directive from the [[Strategos]] on what to do with the being, but nothing comes through. After the battle, as the Third Dignitary Schema are ordered to leave the human bodies to be found, TDS-009 attempts to find the strange humanoid as it wonders why it had not received a directive on it, only to find it gone.{{Ref/Reuse|TMB}}

TDS-009 would later be a part of the [[Battle of Aktis IV]], accompanying Jul 'Mdama alongside [[TDS-002]] as [[Sali 'Nyon's Covenant|traitors]] allied with [[Sali 'Nyon]] are rounded up for execution. After 'Mdama departs aboard a [[Phantom]] for the [[Song of Retribution]] at the recommendation of one of his [[Sangheili Zealot|Zealot]] commanders, TDS-009 was assigned to another Zealot where they quickly run into a [[Carlo Hoya|Spartan]].{{ref/Reuse|TMB}}{{Ref/Comic|Id=HEI15|HE|Issue=15}} During the fight, TDS-009 once again sees the being, now in the form of a young girl with golden hair tucked in a messy bun, again not reacting to what's happening around her. Despite knowing it should attack the Spartan, TDS-009 instead attempted to contact the Strategos to again ask for directives regarding the girl but stopped. Instead, the Promethean kicks the Zealot in its chest, allowing the confused Spartan to escape. In response, the Zealot impales TDS-009 with his [[Domotos-pattern energy sword|Energy Sword]]. As it disintegrates, TDS-009 locks eyes with the girl, who is screaming as she is reduced layer-by-layer into dust.{{Ref/Reuse|TMB}}

Sometime later, TDs-009 awoke in a [[Genesis|Forerunner holding facility]] without any memory of how it got there. After attempting and failing to connect to the Strategos command pattern to obtain operational context, directives, and network with the rest of the Third Dignitary Schema, TDS-009 again sees the girl, now fully grown and dressed in thin grey overalls and a white-blue coat, staring at it from the corner of its cell. TDS-009 attempts to reconnect to the Promethean network again and again, but the woman stares at it throughout. Eventually, TDS-009 attempts to disable its optical sensors and shut down, forcing itself into hibernation to wait for it to be detected by the Strategos and be reconnected to the Promethean network, and to avoid looking at the woman. However, it feels a phantom sensation of a hand lowering its main weapon and then turning its head to the woman, allowing it to take in every detail of her face. Old data and suppressed memories flood into its mind, taking the place of expunged combat directives and strategies,  overwhelming the Knight as it recognizes the girl's face and name.{{Ref/Reuse|TMB}}

As a [[031 Exuberant Witness|Monitor]] and a [[Fireteam Osiris|group of Spartans]] pass its cell,{{Ref/Level|H5G|Guardians}} the woman is now gone as well. Alone, TDS-009 sifts through fragments of memories of its past life.{{Ref/Reuse|TMB}}

==Production notes==
*Sandra Tillson was voiced by actress [[wikipedia:Adrienne Barbeau|Adrienne Barbeau]],<ref>[http://www.imdb.com/name/nm0000105/?ref_=sr_1 '''Internet Movie Database''' ''Adrienne Barbeau'']</ref> who is best known for portraying [[dcau:Catwoman|Catwoman]] in [[dcau:Batman: The Animated Series|''Batman: The Animated Series'']].
*According to a Twitter post by Halo Waypoint, Tillson was born on [[Lodestone]].<ref>[https://twitter.com/HaloWaypoint/status/334403913585414144 '''Twitter''' - ''Today in Halo'']</ref> Her birthplace was changed to Coral in ''[[Halo 4: The Essential Visual Guide]]''. ''Halo: The Machine Breaks'' rectifies this inconsistency by stating Tillson was born on Coral, but moved to Lodestone after the Covenant glassed her homeworld.
