Pridka

The Pridka were a blue-skinned telepathic species that existed in the far future.

At their height, they were the preeminent experts of mental disciplines in the galaxy. They created the Pridka Dream Centre to give therapy to the minds of those needing it. Jirenal absorbed the minds of the Pridka at the Centre. The Seventh Doctor was able to free them for the Sensopath's control. (PROSE: Infinite Requiem)
