"The first Dungeon appearance is assumed to have happened thousands of years ago. In the records, it was said that humans have never used mana like we do now," Gilson said.
"Mana Core Formation was found too late, and the first dungeon breakout exterminated 90% of humanity at that time. Although we are not sure if all those records are true, we have assumed that as the truth," he continued.

"But, Hunters were born, and humans learned about their dormant powers. Although we are still improving till now," Gilson added.
"Moving on to the dungeons, there are three types of Dungeons: Blue, Yellow, and Red," Gilson raised three fingers.
