Land of Ooo

The Land of Ooo is the main setting of Adventure Time, and is the home of Finn and Jake, along with all of their friends and foes. It is divided into different kingdoms, of which the most prominent are the Ice Kingdom, Candy Kingdom, Fire Kingdom, Cloud Kingdom and Lumpy Space, which is technically a kingdom, as it has a princess. There are also many geographical areas not known to be part of any kingdom, such as the Evil Forest and the Bad Lands. Pendleton Ward has confirmed that the Land of Ooo is a continent.

Map
Two different official maps of the Land of Ooo were released by Frederator Studios along with the original Adventure Time pitch documents: the seen in the infobox to the right and a  seen in the gallery below. Of these, the black-and-white one drawn by Ghostshrimp is probably more accurate for several reasons:
 * 1) Its general shape matches the aerial view of Ooo seen in "Business Time" (see picture in gallery below.)
 * 2) A slightly modified version of this map appeared on Princess Bubblegum's hologram map in "The Other Tarts".
 * 3) On the black-and-white map, the names of certain places match up with the names used in the show and by its creators, while some of the names on the color map do not.

Post-apocalyptic setting
Pendleton Ward, the creator of Adventure Time, has stated in an interview that the Land of Ooo is actually a post-apocalyptic world, the result of a global disaster called the Mushroom War, hence the ruined pieces of modern technology scattered across the land.

Humans
It is also possible that Finn may be the sole human being left in Ooo, although it's unknown whether the Mushroom War was responsible for killing off most other humans.
