Arioch
Arioch is the name of a chaotic god that plays a very minor role in NetHack.
Description
When chaotic players are crowned, they receive the title "Glory of Arioch". This title shows up as one of the character's properties seen through enlightenment.
Origin
The name originally appears in the Bible within the Book of Genesis as the name of the "King of Ellasar", who participated in the Battle of the Vale of Siddim. In the Elric series by English author Michael Moorcock, Arioch is the Chaos Lord served by the family line of Elric of Melniboné, the wielder of Stormbringer, which is why the title and weapon are both granted upon crowning a chaotic character.
