This story is a sequel to My Little Balladeer
It was a few years ago that Twilight Sparkle and the Element Bearers sought for aid against a threat from beyond their world, and found it in the person of John the Balladeer. After the threat was defeated he was returned to his world, and Twilight has been searching for her human friend ever since.
Now with Princess Luna's aid she's found him in dreams. Dreams dark and terrible, and haunted by enemies both alien and frightfully familiar.
And this time she and John are alone.
