Plot

A hundred years ago, Godey, the architect who designed an enormous set of musical instruments in Alamos Town called the Space-Time Towers, had a nightmare which he wrote down in his diary, which is later discovered by his great-grandson, the scientist Tonio. The nightmare foretold that two entities that should never have met would cross paths in the space-time rift. Their wrath from this meeting will envelop the town, and cause its collapse. In a garden designed by Godey, Darkrai, a nightmare-causing Pokémon hated by everyone else, opened its heart to a girl called Alicia, who invited Darkrai to stay in the garden. Godey realized the nightmare was telling him to make a music disc for "Orácion", a song with the power to soothe the fiercest rage, for future use. Years later, Darkrai saved the life of Alicia's granddaughter Alice after she tripped and fell from a cliff.
