In Wicked, there is trouble in Oz: the fight for Animal rights is on going. Animals (not animals) have been restricted from all forms of public transportation and are no longer allowed to work except on farms. The Animals are being oppressed and it seems Elphaba is the only human who cares.

"Wicked"
Elphaba is obviously very different from the people in her life. Not only is she green but she was never given much love so she's learned to keep to herself. She's to overcome what people think of her in order to succeed in her life.

Frex is the father of Elphaba and a minister in Munchkinland in Oz. The people of Munchkinland are fed up with the Unnamed God due to the drought and lack of answered prayers so they've turned to idolatry. Frex is desperately trying to turn them back to traditionalist religion and is somewhat succeeding after a very long time of preaching and arguing.
