Set five years after the epic conclusion of Nemo defeating the Nightmare King, he returns to the dream world with Icarus, going on a new quest with Princess Camille, Professor Genius, Flip and the Boomps in a strange new land that may prove to be far different than anything Slumberland has to offer.

When Princess Luna senses that new people have entered the dream world and have come to Equestria, a brand new adventure will come together as the Mane Six come to meet the unlikely heroes of Slumberland for the first time.

At the same time, a darkness is rising again, one even more powerful then before, and with it may be new dangers that even our heroes can't stop...
