Star Swirl the Bearded - a unicorn presence so prominent even in death, that it's said some of his magic still lingers at his grave.  And every century, a powerful burst of energy comes from it, rumored to grant a unicorn, if ever briefly, a burst of immense magic and knowledge like that of Star Swirl himself.

But when Twilight decides to travel with her friends to investigate, it proves to have unforeseen consequences.  For they were unaware that in that same moment, in another world, another kind of magic was activated.  And in the clash between the two, a pathway was unlocked - in more ways than one.

With Twilight now bearing a new power as a result of the strong energy flux, she and her friends find themselves in Blithe's Hollow on the very night that the witch's curse is activated.  With only the words of Star Swirl and remnants of his magic to go on, Twilight and her friends must not only aid Norman in stopping the witch's curse, but discover the nature of Star Swirl's message and why a connection was unlocked a connection between the two worlds - both the living and the dead.  

A ParaNorman crossover story that I and a friend of mine came up with.
