Paintings adorned all four walls of the entertainment room. Duanmu Huai didn't know the order, but fortunately, numbers beneath each painting saved him the trouble.
Upon cursory review, Duanmu Huai discovered that the majority of these paintings depicted ghouls. The first painting represented Arkham City; with city-dwelling Arkham citizens illustrated in the upper half and, beneath their feet in the sewers, hordes of ghouls scurrying about like rats.
The second painting depicted a number of ghouls infiltrating a household unnoticed, stealing the baby, and replacing it with a loathsome, little ghoul in the crib.
In the third painting, the kidnapped human infant seemed to have grown into a child, under the tutelage of the ghouls, learning to gnaw on corpses. The painting split in two showed the substituted ghoul child growing too. Despite appearing human, the twisted, malicious grin on his face gave him away.
