Jordanna's Syndrome is a constellation of symptoms occuring after a viral infection in Mystic children, usually only seen in those under the age of 12. It is fairly rare, affecting only about 1 in 1,000 children, and there seems to be a genetic component as well. In those children that do develop it, it is almost always fatal. Children who manage to survive past the age of 16 will usually not die as a direct result of the disease, although they remain vulnerable to infections for the rest of their lives and will be rather frail in constitution.
