Until the will of the earth awakens and gives people over the age of 18 the power of digitization, that is, the entire earth is gamified. The earth no longer produces any resources. The only way to obtain resources is through life skills or killing Warcraft. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
