answering some quick questions!
Since we were asked and figured it would be good for the whole game to know:
*There were disappearances/replacements happening worldwide, not just Xavier's! Everyone's been returned to their bodies, but it has been being talked about (possibly even some small countries' leaders being swapped and that causing political issues!)
*The non-Skrulls that came also did some clean-up after and removed 99.9% of the alien tech and leftovers from the world war (yes people are unofficially tossing around the phrase WW3!), much to the disappointment of many tech and weapons companies :(
