If you remember FE's theory about the skeletons near Esthar:
Well, in that 'Flood' painting, maybe it represents one of the Kislev...
"27 Kislev - (2105 BCE) - Flood rains cease
It is said that the forty days and nights of rainfall which covered the face of earth with water in Noah's time ended on Kislev 27 of the Hebrew year 1656 (2105 BCE). The flood itself lasted a full year (According to Genesis 6-8)."
Would that explain why you see these big skeletons near Esthar?
In the past, Esthar was underwater. So this must mean flood. This disaster has brought these big monsters (skeletons) to the area, why else skeletons were there? How did it all start in the first place? Lunar Cry?
Now in the present, no more flood! no more water on Esthar! The ground is so cold, desert and almost clean. The skeletons are quite visible.
