Join Lev on his travels, through ancient temples, secret passages and an old mine that's not as empty as it appears... Solve riddles; survive battles and help the goblins as they try to rid themselves of a colony of Cave Spiders. Never losing sight of the burning question: who were the strangers that attacked Lev's family in order to get their hands on the book he and his sister found? How did they know about it? And what do they want with it
