The Void is the final resting place for cats who don't believe in either LightClan nor Shadow Forest. Many loners and rogues will end up here. While these cats can communicate with cats from both LightClan and the Shadow Forest, they don't tend to do so and are considered the independents.
While the Void isn't as terrifying as the Shadow Forest, it's not as peaceful as LightClan either. Those who reside in here waver between the other two or simply don't belong in them. Thank of it as almost a combination of LightClan and the Shadow Forest. Cats here spend most of their time milling around until they are forgotten. Instead of generally appearing in dreams like cats of LightClan and the Shadow Forest, they will wander around the territories like ghosts.
