April 27, 2190.
Exactly 120 years ago, humanity fell into a catastrophe that nearly wiped out civilization from planet Earth.
Thousands of mysterious portals appeared across the world, unleashing millions of creatures never before seen on Earth.
From hordes of orcs flooding the streets of New York to dragons rampaging in Beijing, humanity was cornered and forced to live underground.
For over a century, humans adapted in this condition and began harnessing energy from the portals for their use.
Following our protagonist—Angga, a hunter and a healer who explores portals and slays monsters for a living.
We will also witness humanity's struggle to reclaim their home—surface.
