So, this is a maybe odd idea for a dnd campaign. I want to set it inside a single city hit with a plague. The city is underneath a Dalaran like sheild that locks the city off from the outside. The campaign ends when the party either cures the plauge, lifts the sheild, or escapes the city. Other than that, you would just exist in a city that you lived in that progressivly gets worse. You know people already. Had a job of whatever type, and so on. We would begin on the day the sheild goes up and people realize that supplies will be tight. People you run into would be certain to be seen again. Its not a game type i have ever run before and have always wondered how it would go.
