Juiblex

This being is a demon prince, not typically thought of as a deity, but it may be as powerful as a greater god. It has few worshipers among humans or demi-humans, mostly among chaotic evil humanoids and other such creatures.

When discussed, it is typically referred to by nicknames so as to not draw its attention. These include the Lord of Ooze, and the Big J.

This being is often misnamed as Jubilex, to the point where speaking that name is just as dangerous as speaking its actual name.
