Justice League of America Vol. 3 (2013-2014) #13

Plot

Having travelled through the prison designed for his companions in the Justice Leagues, Martian Manhunter has learned that while there are walls surrounding them, it is their weaknesses that are imprisoning them. Green Lantern, for example, is plagued by paranoia that the people of the world are ungrateful and racist toward him for being a Muslim. Though J'onn's guide, Jason Rusch has disappeared, the Martian is aware of another presence following him on his journey.

That journey next takes him to the prison designed for Madame Xanadu, and the horrors he sees there leave him speechless. Worriedly, Stargirl promises to come for him, but he warns her away. Xanadu has been trying to use magic to escape her plight, but none of the usual channels has worked. So, she has turned to dark magic instead; becoming evil to fight evil. Rather than stick around for that, J'onn decides to move on, continuing to warn Courtney away from following him.
