In the realm of the labyrinth, the number of people had already dropped to four hundred million in the first twelve months within the labyrinth. The creatures were killing at an extremely fast speed, even though a few million had been killed, there were still a few million more of these creatures.
In various parts of the labyrinth it was possible to see groups fighting against these creatures when the creature was of higher levels, the group could only run, because it was certain death if they fought.
