Will the golden witch truly revive?

Note: The story is divided into episodes: four "Question" arcs. Each episode keeps the same main characters, but ends in a different way. However, each episode gives valuable answers, hints, and clues to the previous one, while at the same time bringing forth even more mysteries.
The question arcs are: Legend of the Golden Witch, Turn of the Golden Witch, Banquet of the Golden Witch, and Alliance of the Golden Witch.
