Matrix (Earth-7954)

The Matrix is an alternate dimension that projects and simulates the real world, which was created by the Architect under the Locust Horde to keep the minds of humanity under their control. Although it presents itself as photo-realistic to its inhabitants, the Matrix is actually green tinted.

Background
In the late 23rd century, humanity discovered a new form of energy named Imulsion, which guaranteed limitless energy for Earth without the need of other non eco-friendly fuels. However, unknown to everyone, Imulsion started to "evolve" umderground, which caused the birth of creatures known as the Flood to be born, and wage war against a then-unknown race known as the Locust Horde, hidden from millenia, which forced them out of their homes.

The Second Renaissance
Six weeks following the end of the Insurrection, the Locust Horde submerged and invaded Earth's surface, attacking many major cities and slaughtering millions, in an event which would become known as the Second Renaissance. In the first hours of confusion, the UEG believed the attacks were products of the Insurrectionists. It was only when the President of the United States announced the enemies were not human that humanity learned they were not alone in the universe.
