The Savants were a science-based group of Tigellans. They wore white clothing and had bowl-like haircuts. Their hair was always white.
History[]
The Savants lived in a society with the Deons, whom they often argued with in a science-religion debate.
The Deons did not allow the Savants into the power room where the Dodecahedron was kept. This angered the Savants who wanted to experiment on it. The Savants were arrested after the Deon leader, Lexa, staged a revolution. They were released after order was restored. Deedrix, the Savant leader, accompanied the Fourth Doctor to Zolfa-Thura, as did another Savant, Caris. There, they defeated Meglos. (TV: Meglos)
