Anima device

The anima device was part of the Omega Arsenal. Ollistra asked the War Doctor to identify its use. On discovering the device was a psychic weapon, the Doctor listed the Ood, Sensorites, and Arcateenians as possible creators. It took away people's free will and allowed the user to control other people's minds. (AUDIO: A Thing of Guile) The Doctor later used it to create a state of peace where both Daleks and Time Lords were farmers. Ollistra planned to use it along with the Neverwhen to destroy Skaro.
