Gaius Helen Mohiam

Gaius Helen Mohiam is the ruler of the Bene Gesserit through most of the first few books. She is also Emperor Shaddam's court truthsayer.

Gaius is the one that tests Paul to ensure he is really human and not an abomination. She is slain by Alia's command when she is viewed as a threat on Arrakis.
