Asala and Illyana
It gets into everything it shouldn't and it's where demons live. Back home someone cracked it open and dumped it all over the place. "Inconvenient" is the nicest thing I can say.
I've been dropped into it before, but if you're there physically it's usually less... like it was. Your magic probably let it stay dream-like instead of putting people into the actual physical Fade. It might not have been sectioned out and definitely wouldn't have been personalized. As far as I know, nobody's really hurt, so it could have been worse.
