Every human being had their own elements.

Fire and Fire reproduced Fire.
Water and Water reproduced Water.
Earth and Earth reproduced Earth.
Air and Air reproduced Air.
Then one day, there was one person who wanted to be abnormal. He didn't want any powers. So he mixed some different grass species to make medicine. He ate the medicine and sure enough, he lost his ability. His soulmate appeared to him one day in his life and the child they reproduced was not normal like his mother. He did not have any abilities like all others had. When the child grew up he reproduced with his soulmate. The child they made was also with no ability.
Centuries had past and this species of human lifeforms gradually became greater than the ones with abilities.
After more years the humans with abilities grew extremely rare,and it was to the extent that they were almost extinct.Who knows where they might be now?
