Prince Prospero and his one thousand friends in the Abbey.
The prince entertained his thousand friends at a masked ball of the most unusual magnificence where everyone danced in seven different rooms. Each room represented a different stage in life.
While the party was going on, there were many people in the crowd who had found leisure to become aware of the presence of a masked figure which had arrested the attention of no single individual before . His mask appeared to show the Red Death but soon, everyone realized it was not a mask and he actually had the Red Death.
The Red Death killed Prince Prospero in the seventh room which represented death.
Everyone within the abbey soon died of the Red Death as well.
