I want to know the answer to the following question:
Who oversees the period of reckless behavior?
All the background I'm provided with is that "The festivities end on Ash Wednesday with elaborate funeral rituals marking the death of King Carnival, who is typically burned on a pyre in what is called the burial of the sardine (enterrament de la sardina), or, in Vilanova, as l'enterro.". Is that enough to answer the question?
