Mindcore

The Mind Core served as the collection of the Skith race's greatest minds and the sum of all Skith knowledge. They were used to advise and to supervise the commanders and their subordinates. The Mind Core looked like a huge column of light with big disembodied heads. It was usually located in the centre of the Skith command ships, like the Oppressor 1.
