One month has passed since Rainbow Dash and Applejack have admitted to one another of their feelings. During that time they have grown closer and their relationship has flourished. They feel that what they have is true and unquestionable.
Then one day Twilight comes to them with an urgent letter from the princess. Twilight is asked to gather her friends and meet with Celestia at the castle for unknown reasons. During their time there they cross paths with a mysterious unicorn of unknown origin. He has no name, no face and no remorse. A face covered by a hood and body coated by a robe it is up to the Mane 6 will have to uncover the truth to who this pony is and what his intentions in Equestria are.
His power is unknown even to the princesses and that is what makes him a fearsome foe.
Can the Mane 6 find out who he is? Can they discover his power? Will Rainbow's and Applejack's new found love survive this trial?
