内容简介：
Joseph Erift and Eric Castis were relieved to return home after their first adventure. Joseph still couldn't believe the events that had occurred. They saw real Magic, met new friends, and even new enemies. Even though Joseph and Eric had failed to prevent Ryan Morter from breaking the Protection Seal at the Sealed Forest, they were assured everything would be okay. However, Joseph could tell that their journey was far from over. One day, Joseph receives another letter from Professor Ben Thessit, the enthusiastic researcher who had first wrote to them over a year ago. The letter asks them to come back. After sneaking from their homes and returning to the Murean Islands, Joseph and Eric are quickly plunged back into chaos. Ryan Morter has been restrained by the SIA, the same secret government organization that now threatens to shut down Professor Ben's research. Two demonic servants roam the earth in search of their passage home, showing no remorse for anyone that dares to stop them. What's worse is they seem to know Joseph's ties to the events unfolding around him. Even with the help of new friends and old enemies, Joseph is unsure if they'll make it home alive.
