Knight Terrors Detective Comics #1 (Of 2) Cover B Bernard Chang Card Stock Variant

BATMAN TRAPPED IN THE NIGHTMARE REALM! Jim Gordon stumbles upon a sacred ritual held by three disciples chanting around an enchanted clock...and one of them is wearing the robotic Batsuit that he donned many years ago as Batman...except this metal suit seems to have have soldered directly into the flesh of the wearer! What do these creatures want with Gotham, and why are they targeting Jim's daughter, Babs, too? This has to be a dream, right? Or perhaps it's a nightmare, but if you die in it, you can die in real life as well...
