Time benders are rare beings who have discovered the way to manipulate one of the most basic elements of reality itself, time. Time benders have it within their power to extort time to their own ends, whatever they may be. In order for a time bender to survive the strain placed upon their mind from distorting time, they need a specially crafted homunculus, designed to clean out the thoughts in their mind that would lead to madness, also known as a fetch. Few time benders live for more than a few years without having one.
