Matrix Betas (Earth-5125)

The Matrix Betas, also known as the Earlier Versions, were two Matrix simulations created by the Architect that resulted in critical failures; one was an utopia for humanity, while the second was nightmarish. Many Programs who survived deletions and became exiles came from these early iterations.

First Matrix
"The first matrix I designed was quite naturally perfect. It was a work of art. Flawless. Sublime. A triumph only equaled by its monumental failure."

- - The Architect to Ludens

Following the end of the Second Renaissance with the Judgement Day, the surviving humans were taken by the Machines and plugged into prototype power plants, where they lost the awareness of reality.
