Fool

A Fool is an empty soul, unfettered in any way by the Curse of Greyface, or any other preconceived notions.

They are best known for their ability to accomplish great things simply by being unaware that they can't.

...and for walking off cliffs.

Children and fools must not play with edged tools.
