The Eclipse was founded by Sylens in order to use its Shadow Carja followers to serve Hades' own ends. The Shadow-Carja were chosen to form Eclipse due to them being easily manipulated through religion and nationalism following their defeat in the Carja civil war, and were made into believing Hades was the "Buried Shadow" god from Carja mythology. They follow Hades in the belief that it will help them to control the machines, and plan to use them to retake Meridian and conquer the world. But, they remain unaware of Hades' true intentions: to reawaken the Faro Plague and destroy the world once again. Sylens was forced to flee from the Eclipse after learning Hades had no use for him and had marked him for death. The Shadow-Carja champion Helis replaced Sylens as Hades's trusted follower.
