For six months, Bruce Wayne has been stranded in Equestria. And for six months, he has desired only one thing: to return to Gotham City.
But Bruce Wayne's journey to Equestria was no act of chance. He soon finds that he was brought to Equestria for a reason, by something as dark and twisted as the minds of Arkham's most notorious inmates. With only Princess Luna to aid him, Batman will have to face a darkness beyond any he's fought before.
