the unknown air of toxicity hit the planet , a huge amount of human population was wiped out , but some survived ... but not without a price ... a curse was lifted upon the human race creating humans with strange abilities .The new creatures wore now known as the Unknown ones or tUo .
They are children from human parents given power to destroy or create .
