In order to lie flat at work, he escaped a disaster. From then on, he and an unreliable muddy book were forced to be involved in adventure after adventure. He made a lot of bad friends, picked up a lot of garbage, and collected a lot of skills. It was impossible to win all the way. The world is filled with smoke and dimensions are collapsing.
