This idea can be picked up by anyone who actually wants to try writing it. I just wanted to get it out there at least. Not sure exactly HOW Evelynn could be brought to Equestria, but I know for a fact she'd be definitely seducing people so she can flay them alive and feast on their pain. One thought of something interesting that could happen while Evelynn is in Equestria would be her having an encounter with Queen Chrysalis somehow.
