The Successor

But the Otherworlders is not the only problem that the world powers now had to face. There is now all kinds of beast and new monsters. 

This is unlike the monsters created by the World Orb. 

The World Orb or to some understanding, the system created the monsters that is usually at one place and could be respawn.

The respawn time is dependent on the energy around that area. 

All of these places when one looks at it looks like dungeons in video games. As such some people began calling it dungeon

Most of these dungeon is in caves, in dark deep abyss, around certain caverns or isolated places from human settlement. 

And most of the military under the world powers usually uses these dungeons to train their soldiers 

Some dungeons are public use and some dungeons are reserved for the world powers that ruled the dominion of that place. 

The advantage of the system, ready-made monsters is that there is a pattern to it.
