Using ancient tools crafted by the elves long ago, humans had built mega cities to protect themselves from the onslaught of demons. Over the years, humans would find more of these barriers and with them they created Inns between the cities allowing rest stops without worry, but after a breakthrough of reverse engineering the barriers, much smaller towns and villages populate the lands. Thus, ushering in a safer world outside of the north.
Lilith, a cursed human, works as a carrier who takes on jobs delivering all sorts of mail all around the world, traversing these dangers. Carriers more times than not have the capability to defend themselves, be it with physical strength or magical strength. For Lilith, that is not the case. Although there is an upside or two to being a cursed, there are far more negatives than positives.
One day, when looking for her next job to take, she came across one that was pushed to the side. It required a delivering all the way to the north, something no carrier would ever dare to do as the stories of what was beyond the Scar scared even the strongest away.
Are those stories fake?
Why have the demons slowly disappeared in the south?
Although it was always worth to take caution, and even if the roads may not be safe to travel by yourself, it made people wonder what was truly up there. If there was any danger to worry about after all these years.
The story follows the carrier Lilith and her journey to the north to deliver a package, yet the package is only the beginning as she discovers how the north became such a barren landscape and learns what she is and her true capabilities.
