The Road… traverses Time—Time past, Time to come, Time that could have been, and Time that might yet be. Some people have the ability to access the Road and travel it from Time to Time and world to world.
Diseased people, (leprosy or any other such fear inducing disease) when traveling, will often times wear a cloak that entirely covers their body and ring a bell as they travel, used as a warning for any others to stay away. Could be used for a disguise or safe passage. ... you meet strangely cloaked people, sometimes ringing a bell. "Please give us something to eat, mighty heroes!" This is time to show how good they are.
