Nibiru

Nibiru is coming.

A long time ago, there were the elementals.

In this time, two more planets, close to earth, are present. The three ruled over all the planets.

The fire, earth, and Lightning elementals are all fine, until the darkness comes alive.

It energy is deadly, and it's wanting power.

Nibiru is otherwise known as 'death day'. The darkness is sending millions of heated asteroids towards all the planets.

One, what she thinks, normal, girl, finds that she is a lost elemental. She controls the ice being.

The other three elementals join forces, and maybe, just maybe, they can defeat the darkness, and stop Nibiru.
