Beyond - Gina Meker

Exactly 1500 years ago, Earth had been pushed to its limits and threatened to collaps on itself if we didn't act in time. Mankind didn't know what to do anymore and had declared our home doomed, our days numbered.

That was, until the supernatural society decided to step up and take actions in their own hands. Creatures we thought never existed suddenly appeared out of their secret societies to safe Earth, to erase our mistakes and begin anew.

They succeeded but parts of the world vanished for centuries due to the climate being completely out of the normal before it settled again and left the world at peace again.
