I would jam Diablo's Soul stone into my skull making me the new Lord of Terror, Then i would ressurect King Leoric to lead my armies of skeletons! I will release Shenk The Overseer to coordinate the attacks on Harrogath fortress of the barbarians. The world will be mine!! The earth will crack open spewing the underworld onto the mortal realm it will be chaos! Andarial naturally will be my first choice as a leader of the armies, her loathing for the mortals had bestowed upon her a vengeance unlike any other. Mephisto shall be my advisor, on the battles. We must ride for Khaza'Duhn keep!
