Your objective is to save the valley from an evil Count, who is intent on taking control of Trutania. The only way that he can be stopped is by someone reassembling the hexagram. Unfortunately, the pieces have been scattered all over the valley through the ages. There is also a forged piece, which if placed in the hexagram, will cause an enormous explosion, which will destroy everyone and everything in the valley.
