When king Imur Nesser of the Kingdom of Valencia tried to conquer the whole continent by force, he used the Black Energy to move the gigantic ancient man roaming the desert.
The Aakman Tribe, as self-proclaimed guardians of the ancient civilization that created the ancient man, kept interrupting the king's plan. For that reason the king used all the force he had to slaughter the tribe.
It's said that a disaster devoured the Great Desert after the massacre.[1][2]
