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 War 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.
