A deadly disease has truck and is killing everyone. It makes people feel dizzy, bleed out from their pores, and feel sharp pains.
Prince Prospero did not care about his people dying. He isolated himself from his people so he would not get the disease.
He isolated himself inside a manor that had an iron gate outside and was very hard to get in.
He brought about 1,000 of his close nobles and court. There were different rooms that had different lights that symbolizes something. There was also this clock that everyone was scared of when it rang.
A couple months later during one of the parties, this unknown masked figure appeared. The prince tried to capture him to find his unknown identity, but he was unsuccessful. Instead the masked figure chased the Prince around the manor.
