Once upon a time in the land of fairy tale war had erupted. The four kingdoms Ventus, Terrain, Aqua and Agni were fighting for dominance over the land.

The issue was that the people of each kingdom possessed an unique infinity of magical element and if they touch each other they disappear. The people saw this has a sign that they couldn't coexist together which gave birth to hate.

Has the fighting continued the hate between the people was also effecting the Aeon in the atmosphere turning them negative.

First poison plants appeared in locations where fighting took place. Then the fishes in the lake started to die. Then they came. The devils.

They first hid themselves in the citizens and just when their numbers grew to a hundred they attacked the ventus kingdom. They were savages the sucked the Aeon of any living thing and the Ventus kingdom was destroyed.

This was a wake up call for the other three kingdoms and they stopped fighting amongst each other. They forged an alliance in order to defend against the devils.

With much casualties they manage to seal the devils inside a book. The book came to be known has DevilMa.

After the devil war they found a new appreciation for one another and merged their kingdoms together to created the Triprima kingdom. 

And now after a 100 years in the present the book of DevilMa has been stolen. This has caused a huge uproar in the kingdom. Who could have done it? And what is their purpose?
