Sandra Tillson

Doctor Sandra Tillson was the leader of a team of scientists serving onboard a UNSC installation near one of the Halo installations.

Personality
She was very dedicated to her research, also caring greatly about her team, many of whom were killed in the initial Covenant attack against her station.

History
Little is known about her history. However, due to records accessed by Cortana, it was clarified that the doctor was fifty-one years old during the events of Halo 4, and that she had graduated from the Pegasi Institute, as well as the fact that her doctorate was in Archaeology, and that her middle initial was K.

Composer
As the Master Chief, who had secretly pursued the Covenant fleet-- a small armada, led by the Didact-- attempted to convince her to leave the station, numerous security troops and scientists under her command began to flee.

Alas, the Didact sought a device her team had retrieved, and so many were slaughtered as his vessel tore a hole in the station's side and ripped the artifact, a weapon known as the Composer from its holding chamber. Mere minutes later, the Forerunner used the device to murder Doctor Tillson, as well as every organic being onboard the installation, save for the Master Chief. Using the Composer, the Didact 'composed' them-- destroying their bodies in a grotesque and most likely painful peeling back of the layers of the body, from skin to muscle to vital organs, to skeleton, and finally causing the entire body to disintigrate to a pile of ash.



Any remains of the 'data signatures' that emanated from these piles of ash, including that of Doctor Tillman, was either erased or collected by the Didact, and later destroyed when the Master Chief eliminated both the Didact and the Composer.
