"What's this Trickster all about, Joseph?" I asked him while I looked over his chalkboard in the library.
"The trickster is very similar to the shape shifter, in that he or she is an agent for change, but the difference is that the trickster will poke fun, while the shape shifter is not who he or she pretends to be. Either could lure the hero to his doom, or act as an ally - depending."
"Depending on what?" I asked.
"The plot of the myth, the character of the hero." Said Joseph.
