The Emperor's Soul

A short story by Sanderson which earned a Hugo award. Much of the feel from this seemed to be the inspiration for the soulcasters in his Stormlight Archives series. Like other worlds, this has a magic element which allows for “forging” – modifying the history of an object to change how it appears today. For instance – rewriting the history of a neglected table to have been cared for in order to make it strong a beautiful today. What about rewriting the past of a person? Would that change their soul?
