Demon Abyss

Demon Abyss was a world of its own.

Home to more than a billion abyssals, its size was roughly equal to that of earth.

The hierarchy of this world seemed simple at a first glance.

There was a Demon King at the top of the pyramid. He had four archdukes—peak level 9s—to lead his kingdom.

The ones below archdukes were dukes: Level 9s, but significantly weaker.

Dukes managed duchies and archdukes managed Dukes.

Then there were princes and princesses.

Just like how only outstanding level 9s could be termed Dukes and Archdukes, only the most outstanding level 7s and level 8s were called princes and princesses.

If Demon King was the foundation on which the entire demon abyss exists, Archdukes were the main pillars holding the weight, dukes the pillars helping them.

Princes and Princesses were the future pillars.
