This world does not stand still.

The land drifts.
Creatures change.
Nothing remains the same for long.

Over time... most beings lose themselves.

They become something else.
Something unrecognizable.

Monsters.

These monsters spread a strange, unstable force -
one that slowly erodes everything it touches.

No one knows when it began.

But the dwellers of this world have learned one truth:

Those who can hold onto themselves... can survive.

Some carry a mysterious power -
a force that anchors them,
that keeps them from changing.

But when that force fades,
a being cannot remain whole.

They either disappear...
or become monsters, with no way back.

Yet, a few have discovered something more.

Through sheer will,
they awaken a power from within -

A form shaped by their spirit.

The Marble.

The Marble is the only force that can resist the chaos.
The only force that can break the monsters apart.

And when Marbles collide...
they resonate.
Growing stronger together.

Now, a small group of young heroes -
each bearing a Marble - have begun to realize something.

Their power does not just protect them.

It changes the world.

Little by little...
it brings stability back.

So they make a choice.

To leave the safety they have known.
To explore the drifting islands.
To uncover the truth behind this ever-changing world.

Because something is wrong.

And perhaps...

this world was not always this way.
