Nyarlathotep shifted forms mid-sentence, a hundred faces speaking with one voice. Each face told a different lie, and all were believed.
Most Nyarlathotep art picks a face. A pharaoh, a stranger, a shape mid-collapse into something else. This piece skips the choice. Nine figures stand in a row: skeletal, faceless, flayed red, carved to stone. None of them is the "real" one. That's the idea the story is making, too. A hundred faces, one voice, and the voice never has to pick a side because every lie lands the same.
What makes the pairing work is restraint. The story doesn't explain why the lies were believed. The image doesn't tell you which figure is speaking. Both leave the gap open, and the gap is where the dread lives. Fill it in and the piece stops working.
The instinct behind it was simple: don't paint the shapeshift, paint the shapes. A single figure mid-transformation asks you to imagine the others. Nine figures standing together removes the need to imagine anything. You're just looking at the congregation.
Nyarlathotep doesn't resolve. Neither does the wall.
