The Land of Ooo, or simply Ooo, is the main setting of Adventure Time. It is the home of Finn, Jake, and all their friends and foes. It is divided into many different kingdoms, of which the most prominent are the Ice Kingdom, the Candy Kingdom, the Earldom of Lemongrab, Wildberry Kingdom, the Fire Kingdom, and the Cloud Kingdom. There are also many geographical areas not known to be part of any kingdom, such as the Evil Forest and the Bad Lands. In a similar vein, there is a kingdom in the realm known as Lumpy Space, but it is in another dimension, and therefore not part of Ooo. It was alleged that Finn was the only human known to live there, but this was later revealed to be incorrect.

Marceline and her mother both survived the events of the Mushroom War, a mysterious and destructive war that ravaged the earth one thousand years prior to events of the series. One of Marceline's earliest depicted childhood memories is of her living in a trailer with Elise, who recounts to her the story of how she met her father.[5] Elise was suffering from an illness, however, attempted to keep it hidden from Marceline as not to worry her. She had her draw a map of the land to get to a secret "club house" where there was supposedly a party happening. However, as Elise's health slowly worsened further, she told Marceline to go to the hide-out on her own, where she was left alone, believing her mother had abandoned her due to her demonic powers.[7] The hide-out had many skeletons of other humans, and their fate is most likely from the same illness Elise was suffering.

During this time, Simon Petrikov—the man who would become the Ice King when he was overcome by the power of his crown—found Marceline in the ruins of a city and gave her a stuffed animal named Hambo to cheer her up; by the events of this episode, she is apparently 7 years old, as stated by Simon.[8][9] The two developed a caring relationship, although the crown ruined Simon's mental health, forcing him to leave Marceline alone.[10][5] During this period in her life, Simon presumably somehow managed to reunite Marceline with her father (possibly by traditionally summoning him),[11] only to be disgusted by his cold and heartless ways. Although she attempted to tolerate his evil and selfish antics, she eventually severed all ties with Abadeer after she discovered him eating fries that she made for herself in a road side gas station after traveling with her father.[12][13]
