Original Dune
This article or section refers to elements from Original Dune.
Chaumurky, also called Murky and Musky, was the generic term for poison placed in drink. This, along with chaumas, was a common tool of trade for assassins during the time of the Faufreluches. As a result, poison snoopers were often deployed by those who could afford them, in order to detect chamumas or chaumurky prior to the consumption of food or drink.
It was known that Corrino Emperor Elrood IX succumbed to chaumurky, which led to his son Shaddam IV ascending to the Golden Lion Throne in 10,156AG.
