Sebastian finally had a basic idea of the set-up of the Doppelganger and Invisibility King's monster inheritance.
Due to his one month of captivity inside the military base of the Atlantian Crimson Fleet, through the time that he spent with Tonado, he already learned a lot of basic knowledge about Oceania, mostly about monster inheritances.
The set-up of monster inheritances was different from one mutated beast to the other, but they generally had a template that they followed.
In most inheritance grounds, the entrance to the inheritance ground was visible and not hidden just like in the Sea King's inheritance, but there were those rare inheritance grounds that hide the entrance.
To get access inside, special requirements had to be met.
As soon as the predators get access inside the inheritance ground, the candidate screening process to get the ideal inheritor starts.
This process was also different in different monster inheritances.
