When Aeon and Naga King flew to the Naga Caverns, Aeon learned the Naga King's Name was Morbidus along with the information regarding the Trial Realm of Life and Death.
According to Morbidus, the Trial Realm of Life and Death has a total of four regions namely, the Naga Caverns, Silverwood Forest, Iron Horn Canyon and Great Wilderness Forest.
Except for the Great Wilderness Forest, the remaining three regions were ruled by three Monster Kings, the Naga King, Silver Wolf Queen, and Minotaur King.
'So the Minotaur Village I saw in the past was not a village but a territory. Good thing I didn't dare to execute my crazy plan back then.'
Suddenly, Aeon felt he made the right choice by backing down because, until today, he believed there were only Captain Grade Monsters in the Trial Realm and not the King Grade Monsters.
