Mary of Jesus of Agreda's Casket

Origin
Mary of Jesus of Ágreda was a Franciscan abbess and spiritual writer, known especially for her extensive correspondence with King Philip IV of Spain and reports of her bilocation between Spain and its colonies in New Spain (now New Mexico and Texas). Her body was reported to be in the same state eighty years after death, the supposed state of incorruptibility displayed by many saints.

Effects
Prevents rotting or decay of organic matter. Cannot function properly on organisms that move wildly and can instead cause their flesh/cells to randomly disappear elsewhere.
