The assault left billions of people dead in the first day. Unfortunately for Adam and humanity, they invaded six weeks after the Pendulum Wars were over and attacked every major city on Sera (this strategy was orchestrated by General Karn). Before the peace treaty between the two Seran alliances was signed, Adam reflected on his pact with the Locust Queen hoping she would not invade the surface. Adam used the last five years to finally create the Hammer of Dawn and end the Pendulum Wars between the Coalition of Ordered Govenments (COG) and the Union of Independent Republics (UIR). Therefore he could not find a way to stop the Lambent in time. However, Adam Fenix was preoccupied during the Pendulum Wars. If Adam Fenix could find a way to stop Imulsion from spreading, thus saving the Locust race, they would not have to invade the surface in order to survive. Queen Myrrah desperately entered into a pact with Adam Fenix. This started a war against the Locust Horde deep in the Hollows, forcing them to leave their homes. Exposure to this Imulsion mutated all biological creatures and became the Lambent. The Creation of the Lambent and Emergence DayДЇive years before E-Day, Imulsion started evolving in the Hollows. However these rumors are merely superstitions and were later turned out to be false. Other speculation exists saying they came from Hell. One such example is that the Locust came from a neighboring planet (or one of its moons) and feed on Imulsion. Many theories on their origins have been suggested by the remaining human population. To most of the people on Sera, the historical background on the Locust is generally unknown. The children of the Sires had Lambency in their cells and were mutated from birth, and so the first Locust were born. Fearful of the media and political response towards these mutated people, the scientists of New Hope sealed the Sires away and took their children to Mt. This resulted in the creation of the Sires (predecessors and parents of the Locust Horde).

Unfortunately, the Imulsion began to mutate and an early form of Lambency took hold. The infected members of the population were gathered by the COG (Coalition of Ordered Governments) and moved to New Hope where it was hoped a cure could be found. During the start of the Pendulum Wars, many of the Imulsion miners who had taken part in the Gold Rush began contracting a serious illness after extended Imulsion exposure.

The beginning the of the Locust Horde started at the New Hope Research Facility. 1.3 The Battle and Eventual Destruction of Halvo Bay.1.2 The Creation of the Lambent and Emergence Day.Any type of negotiation with the Locust failed and would lead into the events of Gears Of War. When the Locust made their appearance known, the event became known as Emergence Day or E-Day. This civil war lasted for an unspecified time but it eventually forced the Locust out from the Hollow and invade the surface (this happened six weeks after the Pendulum Wars ended). While this conflict was happening, the Locust were fighting other Locust that were infected with Imulsion (the Lambent). This war would be known as the Pendulum Wars that lasted for 79 years. These tunnels were spread out throughout the planet while different groups of humanity (COG and UIR) were at war with each other over Imulsion. They originally live a subterranean lifestyle beneath the surface of Sera by underground tunnels (known as the Hollow). The Locust Horde are the main antagonists of the entire Gears of WarВ video game franchise. ~ Chief of the COG Defense Staff, General Bardry Salaman describing the Locusts. We can't even begin to negotiate with them, or work out their objectives, because we just don't know the first damn thing about them.
