An event in the history of Natura.
The Naturan Plague was an epidemic that lead to the death of thousands. This illness, caused by bacteria, attacks the heart and lungs, eventually leading to death. This disease appeared suddenly and killed many people and animals alike. A cure was found by doctors, and was given to the people who fell ill with the disease, though the damage to the lungs and heart would be permanent. Even though the spread of the disease was stopped, many of the people who contracted it and were "cured" have a drastically shorter life expectancy due to the damage the bacteria caused.
