Grinsia

The world of Grinsia was created by twin Goddesses. The elder sister
created the winds and the skies and the younger sister brought forth the
land and the sea, as well as the beings who were to inhabit the world.

The Goddesses, having completed their creation, imbued six relics with
remarkable powers to give life and energy to the world they had created.
By doing this they made a promise to those who inhabited the world that
their peace and well-being would last forever.

Many eons have since passed since and humankind has flourished under
watchful eye of the two Goddesses. An ‘Empire” soon arose out of the
ashes of constant warring and created an advanced civilization using
machines.

In a far-flung section of the Empire, ancient ruins, long since
forgotten, have been unearthed.

A family of three treasure hunters soon find out about the treasure and
go out in search of it for, fortune and glory.
