Prompt: Ahead, over a dune of gray sand, rises a tall grid made up of countless squares, extending from the ground to the sky; this is the wall protecting Omega's data. You cut into it, and at a short distance beyond, you see a black mountain with flames at its peak and a door of ice at its base. In the middle, there is a window. On the sides of the mountain, there is a forest of leafless dead trees, submerged in high gray drifts of ash. Black and white hatched illustration.
