King Sombra has returned, unleashing an attack like none other on a defenseless Equestria. Luckily, the Princesses were able to use enough magic to transport everypony to a nearby planet, where they will temporarily take shelter from the horrors of Sombra. But the Mane Six have stayed back defend their home planet. This will prove to be their most difficult and dangerous challenge yet.
