On the brink of extinction, humans turned to ancient elven tools found hidden away in ruins. They were tools to create large barriers that kept the demons at bay. The barriers allowed humans to create mega cities and to recuperate and grow. Now, hundreds of years later, as humans reverse engineered the barriers, and created even more safe areas, humans ushered into a new era of humanity. One that was safer outside of the north. Lilith works as a carrier, someone who takes on the job of delivering mail all around the world. A dangerous job since, even though the population of the demons has dwindled, they still exist. These carriers are as strong as any other warrior or mage except Lilith. As a cursed human, Lilith possesses a near endless amount of mana but is incapable of utilising it. She’s capable of feeling the magic around her, transferring her mana from one thing to another, and creating a pocket dimension to store things in, but that is the limit of a cursed human's current capabilities.  While looking for the next job, Lilith came across a request with a rank requirement far too high for the average carrier. Warned of its dangers, Lilith was the only one capable of bringing such a large item to its northern destination across the Scar, a place forsaken by humans, elves, and dwarves alike. The north was now a mystery, and no one knew what demons wandered around. Was such a place as terrifying as the stories told? Lilith would soon find out what the north had in store for her as she makes her way for one of the most dangerous deliveries anyone would ever see while also uncovering a history of the cursed ones and how much they tie together. 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.
