"Where the heck is Roburu!?", Gigaru, yet another goblin, raised his voice. He looked around trying to find any trace of Roburu but he found none. He then looked toward five other goblins who were beside him. Looking at them he said. "Go find Roburu."
Gigaru was the right-hand man of the goblin king, while Roburu was the left-hand man.
The goblin king was also a conqueror, though he wasn't a player.
Monsters are born with their own class and the goblin king got his class as a conqueror. Conqueror's are respected by many people, and hated by many at the same time.
Regardless, they had the ability to conquer the land and expand it, however, the restriction was imposed based on their level.
The lower the level, the lesser the land they could directly rule on.
