Red herring

The Red herring is a quest item used during The Fremennik Trials quest. Once it is cooked, it will become a regular herring, but a new item, sticky red goop, will be created. Once the puzzle involving the red herring has been completed, the herring can be consumed.

Trivia

 * In mystery novels a red herring is a plot device in which a seemingly important clue is, in fact, unimportant or misleading; during the quest, however, the Red herring is just the opposite and is very important.
