The Inner World of the Synthetic World was like a Dungeon.
It's divided into seven areas—six large areas surrounding one small but crucial area.
These six areas were divided based on the characteristics: Life & Death, Space & Time, and Order & Chaos.
The process of conquering a Synthetic World was fairly simple.
You had to pick an area, cross it and reach the central area. This central area would contain the 'command center' that would grant you ownership of this World.
For a makeup of teams that the Duchies had, this was an easy task. With the protection of Sovereigns, there was no danger either.
That's why the princes themselves came.
But the moment they entered the Inner World, they realized something was amiss.
The good news was that the resources, aura concentration, and treasures were higher than in any normal Synthetic World.
The bad news was that the beasts were far stronger. The environment was way more hostile.
