For a thousand years, humanity has been confined behind the large, overarching walls that protect them from the outside world. It is said that before the age within the walls, humanity ruled the world, overpowering the creatures of this land with their overwhelming magical ability. However, now humanity is but a shell of its former self, forced to live within walls that only hold a few thousand people, only sending out a select skilful few each year to explore the world beyond the walls. Most never return, and those who do bring back scars, both physical and mental.

The curiosity that humankind possesses is an ember that no matter how small it glows, will never truly fade. A group of aspiring adventurers that seek to know what lies outside the walls don't plan on waiting until they're of age to be selected, the group they call themselves as "The New Explorers".

What waits for them outside the walls is true hardship, creatures that are beyond their greatest imagination, beyond their deepest, darkest fears.
