The story of "Two Worlds" begins in an age torn by war. The Orcs have advanced to the south bank of the river Gon and are threatening the Kingdom of Cathalon. While this is happening, the hero, a wandering bounty hunter, is searching for some clue as to the whereabouts of his sister, whom he hasn't seen since her settlement was attacked three years ago. He unexpectedly receives vital information from a mysterious stranger - and immediately joins a Dark Brotherhood (or so it seems). Now the time has come for him to try understanding the game's powerful forces - and to learn how to use them! This is the only way the hero can survive - and get the answers to the questions that are burning in his soul - Who is behind this secretive kidnapping? Will he ever see his sister again? Where is the Tomb of Aziraal - and what role does the mysterious, yet helpful stranger have to play?
