A darkner is any of the members or creatures that live in the Dark World in the video game Deltarune, as opposed to members of the Light World, aka the regular world. Their appearance usually corresponds to their region, as does their name. As of now, there are two regions in the Dark World that they inhabit, the Card Kingdom and the Cyber World, with each introduced to their respective chapter of the game, but there will likely be more regions as new chapters are added.
