Eighty years after humanity defeated the supernatural Tower, the world is still covered in the endless magical Jungle, a place where monsters roam and even the very trees will devour you whole. Josh is a reclaimer and a scavenger, someone who helps cut back the Jungle and find what artifacts of the Old World he can.

But one day, Josh discovers humanity's worst nightmare. An impossibly powerful monster, more than strong enough to wipe out the last City in the world, rests nearby. Thanks to Josh, now it knows that there are riches to be had, and it prepares to escape its prison and burn its way to its prize. He has less than a year before it escapes. No one believes him, he and his friends have been branded criminals and forced to flee. In less than a year, they have to grow strong enough to force people to see the threat and fight.

Josh has only one advantage: Before he found the impossible monster, he found an impossible treasure. An artifact to give someone a new class, something beyond the eight base classes inherited from the heroes who saved the world. This class is the reason they have no allies, the reason paranoid government officials and greedy criminals are chasing them down. With this new class, he might be able to turn everything around, to finally save the world for good.

It is a [Crafter] class.
