A new crisis has arisen that threatens to end the lives of all who would serve the King. The evil warlock Medivh has begun draining the soul of the land itself to increase his dark powers. You must take a party into his tower and destroy him before he summons enough energies to devastate all who would oppose him. Beware his mastery of the black arts, for legend speaks of his ability to command daemons of Hell.
The Last Guardian described the place of Medivh's death as a cave with simple iron furniture, and Warcraft III showed the place to be a fiery dungeon. Both depiction may be a reference to this mission.
