An old legend has it that there was a demon that used humans as its test subjects for body modelification. He cloned, fused and modelified numerous beats and human bodies with his magic. It was said that one of the test subjects that came to possess great power escaped the laboratory and created a tribe among humans. The leader of the tribe is known to have developed a mysterious ability called Demonic Eyes of Petrelification. The demonic eyes, very similar to the cursed eyes of a rare beast Basilik, are known to have the curse to turn everything they stared at into stones.
