Heroes of Might and Magic: Quest for the Dragon Bone Staff

Darkness reigns. Sinister creatures stalk the innocent. King Argus III lies helpless and unconscious, dying from the assassination attempt that has left him poisoned and weak. Malazak, the revenge-driven son of the Wyrm-Father, awaits King Argus's death so he can divide the kingdom between himself, a demon, and a dark minotaur. Only one possesses the power to set things right. You must find the DragonBone Staff.
