The heroes that we're all familiar with - Captain America, Iron Man, Hulk, Black Widow, Captain Marvel, the ones who help and look over us, are all gone. They have disappeared to some great void to fight a war that none of us really know about.
Life still goes on, here on Earth. Children still go to school and eat lunch even as the universe shifts and battles around them. But this allows more sinister things to come out of the woodwork, un-hindered by the watchful eye of the heroes. So new people need to come out, new super humans need to heed the call to defend their neighborhoods, their countries. Who will stand up?
