This seemed to have died down for reasons unknown to me. However, because I am interested in seeing it continue, I would like to offer to make some kind of opposition, or 'bad guys'. It's a superhero story, but up until now there hasn't been much heroic going on. Perhaps Fury shows up and starts some intense trining regimen, perhaps the base is attacked, maybe there's aliens, or demons!
My plan is simply to give the players something to do, and active contribution they can perform to further the story.
However, I'm placing this here so I can see the opinion you guys have on the subject. Whether you think it should be done, how it should be done, or what alternative proposals you have to keep this thing rolling.
