The divine shaping giveth, and it taketh away, as we work our will upon the mortal clay. An entire crop of specimens is lost. Designation A72 is catatonic. Designation A65 removed her face with a shard of glass. The rest gibber in similar states. Designation A59 is the only specimen intact.
The uninitiated refer to them as Twisted Mentats, but that vulgar epithet accurately communicates the process. A specific negative emotion, unique to each specimen, is identified, squeezed, and twisted. Precise adjustments applied to this dial achieves such wonders.
Theory: A59 somehow accessed this information, decided to eliminate the competition, and visited his cropmates, one by one, driving each to madness by twisting their unique emotional dials. Though deftly opening an event horizon in another’s head and achieving such oblivion is impressive, we determined to dispose of A59. However, Baron Harkonnen was so impressed with this display of demoniacal competency, that he is willing to purchase A59 for such a sum as to defray the loss.
