Prospero is introduced. This is during the time of the "Red Death" which was a deadly plaque that was in the kingdom.
Prospero was sure that he could stop the plague from reaching him and his nobles by throwing a big party and inviting the wealthiest people to a masquerade ball.
All of the guests were confused that all of the rooms in the castle were a different color. They did not dare to enter the room with the black walls in the red windows. There was a clock in this room that chimed every hour on the hour. Right before the clock was about to strike midnight, a mysterious creature appeared at the party. He is dressed as if he was affected by the plaque.
Prospero decides to confront the intruder rather than try to escape him.
As Prospero approaches the intruder, he falls to his death.
The guests try to defeat the intruder, but soon realize that there is no one under the costume and they all die as well. Even though Prospero tried to escape the Red Death, it ended up coming for the kingdom anyway.
