The white space is a plane, of which a very large area is visible, but difficult to see details. It reaches the horizon at a point where the overcast clouds fade into a haze, also difficult to see details. The sky is clouded. Later I had to put in a storm, so the entire cloud thing changed. See below.
The cube is grey stone, lit from diffuse sunlight behind me, and to my left. The cube is seen from the corner, only two sides visible. It is much darker grey on the shaded side, but grey on both. The shadow reaches out to the right and away from me, but is soft edged, and not distinct. The ladder is built into the corner of the cube facing my left, as rungs mounted individually into the stone without exterior mounting visible. (Sunk into the stone at each end, it seems.) It goes all the way from the bottom, to the top, but has no side rails, or coaming. It gives scale to the cube, which is now about fifty or sixty feet on a side.
The flowers came with an entire landscape. Flowers don’t grow out of white ground. So, now the plane is a sandy tufted grassland, mostly sand, but with clumps of tall grass, with flowers here and there. There is now evidence of some wind, and the consequent wear to the stone cube, which has somehow become very old. The horizon just got a bit closer, being less than infinite. I can see far enough that the distant clumps of grass merge. They are wild flowers, mostly blue, and small, a few tufts of feathery inflorescences from the grass itself, and a bit of low growing ground cover with yellow and red flowers around the verges of the tuffets of grass. (They turn out to be rather large, five or six feet across on the average.)
Wow. I tried and tried to make it a rainstorm, but it so contradicts what I have pictured so far that I had to start from scratch, and it ends up being a sand storm, broad, and not too high, coming left to right, and very distant. Visibility drops sharply looking into the storm, and the grass before it is strongly bent away from it. The wind where I am is blustery, and filled with dust, I think I will go stand in the lea of the cube. It is here I find the horse. It is an Arabian, deep brown with only a couple of light stars on its ears and nose, and one white sock. It is grazing in the lea of the cube, and starts when I arrive, but does not flee. It keeps me in view, but does not challenge me. I think it is doing exactly what I am doing, sheltering from the storm.
I decide not to climb the ladder until after the storm. Might be dangerous to be caught up there. I see no entrance to the cube on either side I can see, and the wind has risen enough that I don’t want to move around it until things settle down.
