The player character is a dishonored knight hired by a scholar named Charlotte L. Wells to investigate the ruins of Harlech Island on her behalf. Almost as soon as he begins, however, he is mortally wounded by a mysterious warrior named Dvorak and must undergo a life-saving process which binds him to Harlech. He will now die if he ever leaves – unless he can find the fabled Dragon Slayer sword, which is the only item capable of severing his ties with Harlech and giving him his life back.
In the N-Gage version, the player character is instead a hunter who has been hired by a small town named Marion Berck to find a missing girl named Momo who disappeared after King-Dragon attacked. Since King-Dragon's attack, the villagers have been plagued by mysterious deaths, dying crops, and monster attacks, and the players must guide the hunter in the journey to find Momo.
