Mustard is the last fairy you'd want to saddle with the job of saving the world.   For one thing, that's what adults are for, but they're not exactly doing their job, now are they?  For another, Mustard doesn't exactly have any outstanding skills, innate talents, likeable personality, or wisecracking humor.  In fact, she has next to nothing to tilt the odds in her favor.  What she does have are disabilities. A lot of disabilities.  And now?  Now she also has hideously powerful, bloodthirsty magical sword.  A sword of such fury and power that it's fit to end the world in fire and blood. This is Mustard's story.  The story of how and why she never, ever used it.
