This scene was a big challenge to bring to reality. In my mind it needed to incorporate some sense of who the Watchers are and what they represent. In the end I decided that showing the close, interlinked relationship and stature that they all share was the way to go.
The initial sketch does not capture my full vision; I always had stuck in my head powerful silhouettes being back-lit by light. The light represents the light of the Guardian. You may have noticed that throughout each of the scenes streaming light is separated into six rays of light to represent each of the worlds, Watchers and schools. Some of the other details in the scene are Celtic knots both on the floor and the back wall near the ceiling.
