this book is the star of a system series. The US has found out how to make worm hole but they don’t completely understand them. the first time one of this Worm hole is made it destroyed part of a big city. this story takes place in rural Colorado where a small facility is working on making a smaller worm hole. this facility is using an AI name Promitius to with the primary gold of making the energy product by the worm hole usable by all of humanity. exposure to this energy makes the Promitius AI go sapien so he comes to the conclusion that the best way to make this energy usable by every one is by making a system and adapting people to the energy. However he disad that the best way to implement the system is by copying MMO RPG as inspiration.
TLDR an AI used Energy from a magic portal to make System and give everyone classes.
