Head of security (Castrovalva)

The head of security was in charge of security at the Pharos Project.

Biography
The head of security helped his guards apprehend Adric, Nyssa and Tegan after they were seen on the grounds of the Pharos Project on 1 March 1981.

Adric managed to distract the head of security and the guards long enough by pointing up to the sky and supposedly indicating the way into E-Space, allowing Nyssa and Tegan to steal the ambulance which had arrived for the newly regenerated Fifth Doctor and use it to get him to the TARDIS.

The head of security managed to hold Adric and ordered his guards to try and get into the TARDIS. However, the Master's TARDIS then materialised and used energy bolts to knock out the head of security and his guards, allowing Nyssa and Tegan to help Adric into the Doctor's TARDIS. (TV: Castrovalva)
