An open expanse of bright blue. The light feels like it's pressing through, fresh and strong. A slight gradient of lightness, but no sign of another color.
Pressure at the back; something level and smooth, the same temperature all over. The same, if lighter, for other sections of touch. A slight indentation at the extremities. A pleasant texture. Almost sharp. A pleasant cold flow over the rest of the body.
A sound of howling and ruffling. Barometry 83kPa.
