- —Bobby Pendragon on how old-fashioned things to him could be brand-new on First Earth[[[no source]]]
First Earth is the past of the territories Second Earth and Third Earth. As they are all some part of Earth, they are interlinked. In The Never War, it took place in 1937, in the midst of the Hindenburg crash.
First Earth was the third territory to be targeted by Saint Dane. It took place on the same planet as Second Earth, although it was set roughly seventy years in the past. When Bobby visited the territory, the year was 1937. Saint Dane actually did nothing on this territory, but Bobby came anyway. By coming he nearly lost 3 territories. The Hindenburg was being set up to crash. However, Bobby tried to stop it from crashing, which would result in the Germans winning World War II. They would use atomic bombs to destroy every major Ally city. In The Quillan Games, this is the territory where Mark Dimond ran away to after he thought that he had lost his parents.
