The series takes place in a fictional universe consisting of eighteen surviving realms which, according to in-game backstories, were created by the Elder Gods. The Mortal Kombat: Deception manual described six of the realms as: "Earthrealm, home to such legendary heroes as Liu Kang, Kung Lao, Sonya Blade, Johnny Cage and Jax, and also under the protection of the Thunder God Raiden; Netherrealm, the fiery depths of which are inhospitable to all but the most vile, a realm of demons and shadowy warriors such as Quan Chi and Noob Saibot; Outworld, a realm of constant strife which Emperor Shao Kahn claims as his own; Seido, the Realm of Order, whose inhabitants prize structure and order above all else; the Realm of Chaos, whose inhabitants do not abide by any rules whatsoever, and where constant turmoil and change are worshipped; and Edenia, which is known for its beauty, artistic expression, and the longevity of its inhabitants."[17][18] The Elder Gods decreed that the denizens of one realm could only conquer another realm by defeating the defending realm's greatest warriors in ten consecutive Mortal Kombat tournaments.
