Kiamo Ko is a castle located on the peak of Knobblehead Pike in the Vinkus. The castle is owned by Fiyero's family, the Tigelaar clan. It is a location that is featured both in the novels and the musical production.
In the NovelsEdit
Kiamo Ko serves as the home to Fiyero's family: wife, kids, sisters-in-law, and later, a house maid/nanny. Elphaba Thropp arrives here on a caravan accompanied by a mysterious boy named Liir. She stays with the family there, until they are arrested and taken away by the Gale Force. During her stay there, she is known as the Wicked Witch of the West, as she begins to study magic from the Grimmerie almost obsessively.
In the MusicalEdit
Fiyero does not have a wife or children, and Kiamo Ko is described as simply "[his] family's castle in the Vinkus," which is abandoned as they live in another castle elsewhere. He and Elphaba plan to go there to escape the Wizard's royal guards. Only she is able to go, and she takes shelter there, holding Dorothy Gale hostage.
In both book and musical, Kiamo Ko is where Elphaba has her final stand-off with Dorothy.
