Situated at the very heart of the Devil Realm lies The Inner Ring, a region that is home to the most powerful and influential beings in the realm. While the Devil Court, which governs all parts of the realm, holds ultimate power, it is challenged by the existence of a formidable contender - The Hundred Devils Union.
The Hundred Devils Union is a highly influential faction that commands great respect and fear in the Devil Realm. It consists of not just any devil clans, but the cream of the crop, the top hundred devil clans that have proven their might and cunning through the ages. These clans have chosen to unite under the leadership of an entity known as the Archaic Devil Lord, a figure of tremendous power and prestige.
