Slumberland is the basis of the Japanese/American film, Little Nemo: Adventures in Slumberland. A fictional realm, ruled by King Morpheus, Slumberland is said to be the origin point of all of mortalkind's hopes and dreams. It is well protected and guarded by Morpheus and his subjects, including the young boy Nemo, the royal heroine Princess Camille, and the sophisticated Professor Genius, from the terrible forces of Nightmare Land, led by the Nightmare King himself. Slumberland is known for the palace of King Morpheus, as it's main sight. It is briefly featured in the early events of the Disney vs. Non-Disney Villains War, being one of the kingdoms threatened by Chernabog's forces. While not physically featured in Heroes vs. Villains War, Slumberland is represented by King Morpheus and his loyal subjects, as they join forces with the Royal Council, on purpose to prevent the evil forces from attacking their homelands.
