After a week of magic training at Canterlot, Twilight feels ready to take the test Celestia will propose, but she finds out she is required to defeat a creature whose existence only her mentor acknowledges.
In this short adventure, Twilight will have to use all her knowledge and the help of her friends to overcome the difficult trials that lie ahead.
The search of the mythical creature, guided only by the princess' description, will put Twilight to the limit of her strength and imagination.

Note: Many thanks to my editor Thardoc and my proofreaders John_Wheel, Fadri, Thau, Pirita and Encon. I couldn't have made a decent piece of literature without them.
