In possibly the worst day in Avengers history, an unknown assailant caused catastrophic events that would bring about the end of the Earth’s mightiest heroes. These actions left some critically injured while others would die at the hands of their enemies. If not for the aid of Doctor Strange, who uncovered that the attacks were magic based, the Avengers might never have revealed, or defeated, their true enemy- an insane Scarlet Witch.
