Cyber Module

In the late 20th century, Tobias Vaughn had a Cyber-Planner, known as the Cyber-Director or Cyber Module (PROSE: The Invasion), installed in his office at International Electromatics in London where it acted as a communications channel between Vaughn and the Cybermen. It recognised the Second Doctor and Jamie McCrimmon from Planet 14, and urged Vaughn to destroy them.

After discovering that they had two days before Brigadier Lethbridge Stewart reputed to the UN, thus jeopardising the whole invasion, Vaughn and the Director argued whether they should bring their plans forward, as the invasion forces were not complete. After Vaughn stated he would sever all help if the invasion was not brought to the dawn of the next day, the Director relented.

Later, the Cyber-Director went over the plan for invasion. However, after stating they would identify and convert suitable humans and destroy the rest, Vaughn argued their agreement was that he could rule Earth and the Cybermen could take mineral resources. The Director demanded that Vaughn should be fully converted to act as a leader. After Vaughn insisted his mind remains human, the Director relented.

One hour before the start of the invasion the Cyber-Director and Vaughn began counting down until the signal could be sent. After the invasion began, the Director and Vaughn confronted the Doctor, as the Director stated the invasion fleet would arrive in two waves. After the humans began fighting back against the Cyber Fleet, the Director believed Vaughn had betrayed them, and revealed that the Cybermen were going to destroy Earth with a cyber megaton bomb. In retribution, the Director was destroyed by Vaughn's Cerebration Machine. (TV: The Invasion)
