Process
1. The Plague spread from Turkey, Eastern Russia, and Italy.
2. Buboes, Gangrene, Coughing, Sneezing, and Blood from the Mouth and Nose (and any re-wording of the last) are all acceptable.
3. It would be indeed smart to avoid rats.
4. I'll accept ravens, crows, or other darkly portrayed birds.
5. I wouldn't try to escape a plague if everyone has it and are dropping like flies.
