Nihilumbra follows the story of Born, who was created from the Void, the nothingness. When he abandons it and appears in the world, he sets up on a long journey where he will learn how to use the colours around him, grating him powerful abilities. The Void from which Born escaped reclaims him, and it will never stop chasing him, devouring everything on its path. As Born runs for his life, he condemns the beautiful places he visits, as the Void makes them vanish forever.
