Synopsis
Lizardfolk warrior Hisser awoke in the deep fog. But he had no memory of why he was here or what he was doing. It was a young man named Theron who took Hisser out of his dream. "You are a hero who challenged the dungeon and fell down once. It is contained in the mirror by the hands of Lord Chaos who controls the dungeon." Theron is a party of four who are awakened like Hisser. I asked if I would try the dungeon again. Hisser's answer was fixed ... The original novelization of the blockbuster RPG is finally here.
