The ruling power of a medieval magical society has found a way to enter the human world and take their valuable resources. After corrupting political figures and creating a world-scale war in the human world they had retreated into their old world, getting ready to begin the next invasion. A heretic from this world of Snowball seeks to bring about change. Combining the technology of the human world with the magic of his own he developed a system to fight against the ruling powers. The main characters of this story are a group brought from Earth, but due to problems with their assimilation of the system, they have lost their memories. This is an improved and hugely different version of a previous story, with a lot more effort on the editing and much slower publication.
