He’s an American folk artist who worked as a custodian in Chicago, Illinois. Darger became famous after his death, when a 15,145-page, single-spaced fantasy manuscript called The Story of the Vivian Girls, in What is known as the Realms of the Unreal, of the Glandeco-Angelinian War Storm, Caused by the Child Slave Rebellion, along with several hundred drawings and watercolor paintings illustrating the story were discovered.
In the Realms of the Unreal (shortened title) is the story of the 7 daughters of Robert Vivian who are aid in a rebellion in the nation of Abbieannia, working against the evil regime of child slavery imposed by John Manley and the Glandelinians. Children go to war, fighting, and are often killed in battle or captured and tortured.
