Prompt code:
A photo of the ruins of a giant futuristic military installation in a desert. The remnants of a complex of ancient buildings are partially visible rising out of a sea of very tall reddish-gold sand dunes. The ruins are on the edge of the sand sea where a dry river cuts a valley through the sand sea like in Sossusvlei, with a few scattered trees and shrubs in the dried up river bed. In the centre of the complex an enormous spherical structure made out of a futuristic concrete-like metamaterial rises our of the sand, with damage and holes to parts of the sphere's exterior. A primitive town is visible on the flat ground in the valley near some of the ruined structures. A couple of covered wagons are being drawn by horses along a track through the valley to the shanty town next to the ruins.
