Basically in this AU, it was called Chaos_Order (but it was usually known as Chaos_world). It's a black and white colored au besides the horns. Each demon have something called "the Chains", though this can be easily translated to soulmates. How it works is that depending on your relationship, you are able to form a chain which is a special connection between the two demons. This relationship can range to enemies, rivals, family or lovers though there is one thing that must be connected and it is called "Following". All demons is born into two things, the following of Calamity and the following of Tranquility (in simple: Demons are born in chaos or born in order) and opposite attract so a demon born of calamity has a chain with a demon born of tranquility . Each demons also have 4 "lives" though they aren't really lives. For example: A demon dies and this demon will be replaced by a replica who has memories of the dead demon and continues as the 2nd life for the demon. These replicas do not know they are clones and if they knew, they will off themselves. Another thing about the chains is that if one demon are on their last life and dies, the second demon who had a special connection to that demon will slowly become a void and unstable. Now that is all I can give for right now..
