Question: who created the world that wicked lives in

title: Wicked (musical)
text: Meanwhile , back at the castle , Fiyero ( now a scarecrow ) comes to the spot where Elphaba was melted . Making sure that no one is observing , he knocks on the floor and out from a trap door steps Elphaba , very much alive ; the entire thing was a ruse to convince her enemies of her death and to ensure her future with Fiyero , who was transformed into the scarecrow by her spell in the process . Before leaving , Elphaba regrets that she 'll never see Glinda again and tell her that she and Fiyero are alive . Simultaneously , returning to the musical 's starting point , Glinda reports to the people of Oz that the Wicked Witch of the West has been killed and promises to properly earn her title as Glinda the Good . As the people celebrate and Glinda mourns , Elphaba and Fiyero leave Oz behind . ( `` Finale '' )
