Caspar Wistar’s Shutters

Origin
Patient, methodical and keenly aware, Caspar Wistar was the model anatomist. A quick study under the tutelage of Edinburgh’s prestigious Royal Medical Society, Wistar returned to Pennsylvania as a professor and doctor. When yellow fever struck the city in 1793, he administered vaccines to many residents in the belief early exposure would strengthen immunity to worse diseases. Along with his habit of hosting an open party in the winters to chat with private citizens, he became recognized as one of the city’s most prominent figures.

Asides from his college lectures demonstrating life size human skeletal models, he also helped his dear friend Thomas Jefferson assemble bones of the extinct megalonyx ground sloth retrieved on the Lewis and Clark Expedition.

Effects
Opening outwards from any building releases a large plume of dust that envelopes the whole body. After a mild tingling sensation, the user will feel no physical changes asides from taste differentiation being slightly off. Exposure to the first harmful disease or virus causes the body to activate its immune system on a selective basis, wiping out any contagion with minimal harm. Afterwards, those very same users may experience their bones loosening their structure and starting to slide around the body. The user looses some of their form and resembles an amorphous blob until they are no longer able to function.
