Nightosphere (Ooo)

The Nightosphere is an alternate dimension appearing in "It Came from the Nightosphere," inhabited by Hunson Abadeer, Marshalia , and a multitude of other demonic and "deathless" entities. In the episode "It Came from the Nightosphere," a portal between the Nightosphere and Ooo, formed in Marceline's house, led to a place engulfed in fire. Details of the place were eventually exemplified in "Return to the Nightosphere" and "Daddy's Little Monster," where it was viewed to be a demonic wasteland filled with chaos. The dimension can be escaped by going through a portal in Hunson's house. In "The Secret Sister," Marsha mentioned that she was raised and still lives in the Nightosphere with Hunson, although she isn't sees in "Return to the Nightosphere" or "Daddy's Little Monster."

==How to get there ==
 * 1) First draw a happy face (Phil Face) on a surface.
 * 2) Douse the face with some bug milk.
 * 3) Chant "Maloso vobiscum et cum spiritum!"

Trivia

 * It would be impossible to send The Lich to the Nightosphere because he's not from that universe.
 * "Maloso vobiscum et cum spiritum" roughly translates from Latin to: "Evil be with you and with your spirit." This phrase may be a reference to the Catholic liturgy, where the priest says "Dominus vobiscum" ("The Lord be with you"), and the congregation responds "et cum spiritu tuo" ("and with your spirit").
 * The Nightosphere has a demon jail only to maintain the illusion of order.
 * The name "Nightosphere" could be a play on the word "lithosphere " which is used to describe the outer rock layers of planet Earth. The word "lithosphere" contains the past tense of the verb "to light." Because the Nightosphere is an alternate dimension to the Land of Ooo and Aaa and namely Earth, the hypothetical and comical opposite of "lithosphere" with light, would be "Nightosphere" with night.
 * The Nightosphere bears similarities to Hell in appearance, and Finn states, "I'll see you in the Nightosphere, you sick freak." This is similar to the known phrase, "I'll see you in Hell."
