Oz, also known as the Land of Oz, is a world featured on ABC's Once Upon a Time. It first appears in the sixteenth episode of the third season.


Before First CurseEdit

A woodcutter and his wife are travelling to Emerald City when a cyclone drops a basket in front of them. The woman discovers an infant girl in the basket. Only the husband sees the newborn use powerful magic, and out of fear, he attempts to convince his wife to leave the girl behind, but she insists on keeping the child and naming her Zelena. Years later, Zelena's mother passes away while the father grudgingly raises the girl. One day, he admits her true origins. Upset, Zelena goes to the Wizard of Oz about her birth family. He reveals Zelena was abandoned because her mother, Cora, desired to become royalty, which her first-born child could not suffice. Zelena gets a glimpse of her half-sister, Regina, who became Queen and is being taught magic by Rumplestiltskin. The Wizard of Oz gifts her a pair of slippers to travel anywhere she desires, to which Zelena goes to Regina's palace. Later, Zelena, whose envy for Regina has turned her skin green, asks the Wizard to send her back in time to change the circumstances of Cora's abandonment. When told this is not possible, she angrily tears away the Wizard's curtain to reveal he is a showman named Walsh. Zelena makes use of the man by turning him into a flying monkey. ("It's Not Easy Being Green")

Shortly after, Glinda, the Witch of the South, arrives and asks Zelena to join her in Oz's sisterhood of witches. Along with the Witch of the East and the Witch of the North, they believe Zelena is destined to join them because of a prophecy foretelling of a sorceress arriving by cyclone and becoming the Witch of the West. Despite still obsessed about changing her old past, Zelena is convinced by Glinda of her destiny as a witch of the sisterhood. After receiving a pendant to harness her powers, they reach a girl, Dorothy, who arrives to Oz by cyclone. Fearing this child is the actual Witch of the West, Zelena's skin begins reverting to green and she discovers the prophecy also states the sorceress will "unseat the greatest evil the realm has ever seen", which she believes is herself. Zelena fakes her own death after purposely attacking Dorothy, who responds by throwing water onto her. Realizing the prophecy was right, Glinda offers Dorothy Zelena's place in the sisterhood, but the girl wishes to go home. With Zelena is gone, her magic is undone, thus the Wizard returns, or so Glinda believes. In truth, Zelena masquerades as the man to send Dorothy home. After the big reveal, Glinda vows to find another sorceress to fulfill the prophecy, but Zelena banishes her to the Enchanted Forest. ("Kansas")

Following Rumplestiltskin's orders, world traveler Jefferson heads to Oz in search of magic slippers capable of jumping through lands. Though unsuccessful, he does return with a crystal ball that Rumplestiltskin begrudgingly accepts. ("The Doctor")
