Piter de Vries

Piter de Vries was a vicious, sadistic, and brilliant Mentat, and perhaps the closest approximation of a friend to Baron Vladimir Harkonnen. A product of Bene Tleilax ‘twisting’, de Vries served as House Harkonnen’s primary Mentat, working to further his master’s ambitions.

Where standard Mentats are meticulously trained and conditioned to act without base emotion, de Vries’ worst tendencies had all been encouraged. While he still possessed the razor-sharp insight of any other Mentat, he was prone to adding cruel flourishes to plans crafted from the output of his computations. This sadism was highly appealing to the Baron, who valued him greatly but never fully trusted him or considered him anything but expendable.

De Vries commanded an intelligence network to rival that of any power in the Imperium and schemed ceaselessly on behalf of the Harkonnens, and likely, himself. The extent of the evils he accomplished in his life can only be guessed.
