Kehl or Khel is the name of a Tleilaxu secret council.
As it appears it's possibly a council made up of the inner most clan of Tleilaxu Masters and or only made up of the Masheikh.
Behind the scenes[]
Probably from the Pashtun word meaning "followers of". The word is a common final element in the names of clans, tribes and villiages.
