Ace lived his life day-by-day, minding the shop to make more than enough money to live an easy lifestyle. Things were going great, but in everypony's life, a little rain must fall; given inspiration, Ace conducts a dangerous experiment...

After the experiment ends unexpectedly, Ace has to seek out help, and the only pony he knows who might have a chance to help is a total stranger, Princess Celestia's star pupil, Twilight Sparkle.

Grateful for the bit of help Twilight is able to provide, Ace repays her in the only way he is capable: helping her with her magic and teaching her things she may never have learned otherwise.

How long before Ace's lessons get Twilight into trouble? What is a Spell Misfire, and why is Ace the only Unicorn who seems to suffer their adverse effects? Why does Ace's name sound so foreign, and where did he come from? How will Ace get along with Twilight's friends who don't have the same talent for magic? Only time will tell.
