The realm of Gaia used to be a peaceful land until the five-nation declared war against each other for resources and land.
Hoping to solve the problem once and for all, the goddess Gaia decided to pass on a prophecy to a random person living in the realm of Gaia.
She inscribed the prophecy in the form of a scroll and cast it down upon the realm of Gaia, waiting for a fated one to discover the scroll.
The scroll was discovered but... Gaia forgot that all living being has one trait that always emerges when the opportunity is given.
Greed.

The scroll was duplicated and sold to each leader of the five-nation, each nation ceased their war temporarily and poured all their resources researching on the prophecy. All their research has come to fruition after countless efforts.

At the foretold date, all five nations prepared for the summoning ritual...
The ritual to summon...

The Soul Smith.
