The rebuilding of the Black Fairy Mavros' army has started in full swing as she was finally able to convert half of the Grafts that the Elder Dryad Dorn safeguarded. The revived dryad or leshy would then take more unfortunate humans or humanoid monsters to become part of their army. The disappearance of people near the swamp was not a rare occurrence as this area was already sketchy.
As the Black Fairy Mavros was busy overseeing the revival of her army, she suddenly felt a jolt of energy that was incredibly familiar to her. She was able to sense the unknown stone that she got back then which made her rise in power. The familiar feeling was but a split second, but it was enough for her to know where the general direction was. She would have gone to get the unknown stone, but she was confident that she will be the only one that can unlock its power and use it.
