Brethren Moons

Brethren Moons, also known as Brother Moons or Blood Moons, are colossal moon-sized Necromorphs and are discovered to be the true source of the signals from the Markers. They're believed to be the final stage of the life cycle of the Necromorph race and are colossal sized lovecraftian entities that span across the universe infecting and consuming entire worlds and species as a means of continuing the existence of their own kind. Because of their nature and agenda, they serve as the de-facto gods of the Unitology cult religion and they are the main antagonists of the entire Dead Space franchise. They later serve as the main antagonist of the DLC Dead Space: Awakened.
