In the wastelands of what once was Equestria, ponies survive any way they can. No one trust anyone, for even someone you think is your best friend could stab you in the back at any moment. There are those who hope for a hero, but it's been years since a "hero" has even been conceived. Those who claim to be heroes are just there for the fame.

Except for one pony. One day, young but wise Graymane Streak sees the legendary superhero from the Happy Times: Mare-Do-Well. Inspired, he follows Mare-Do-Well and is thrown into an endless spiral of love, betrayal, adventure, and grief. Can he live through it all?
