Three of the stories in this book (Mister Blue Sky, The Man Comes Around, and Misfits & Mistakes) feature The Scrap Pile, The Enigmas, and several other characters that we originally created in City of Heroes. "Mister Blue Sky" has a lot of things that will look familiar if you've ever played the winter event. "A Bad Habit" is also a super-hero story, but it's much older than City of Heroes.
