Finally he stopped feeding them.

Two days after the table scraps had ceased to fall from their desert sky, four black mobiles surrounded an orange and dragged it back to their maw. They maimed it first, ripping off its mandibles and antennae and limbs, and carried it through the shadowed main gate of their miniature castle. It never emerged. Within an hour more than forty orange mobile marched across the sand and attacked the blacks' corner. They were outnumbered by the blacks that came rushing up from the depths.

Kress, delighted, congratulated himself on his genius.

When he put food into the tank the following day, a three-cornered battle broke out over its possession. The whites were the big winners.

After that, war followed war.

Almost a month to the day after Jala Wo had delivered the sandkings, Kress turned on the holographic projector, and his face materialized in the tank. It turned, slowly, around and around, so that his gaze fell on all four castles equally. Kress thought it rather a good likeness; it had his impish grin, wide mouth, full cheeks. His blue eyes sparkled, his gray hair was carefully arrayed in a fashionable sidesweep, his eyebrows were thin and sophisticated.

Soon enough the sandkings set to work. Kress fed them lavishly while his image beamed down at them from the sky. Temporarily the wars stopped. All activity was directed toward worship.

The orange sandkings, as usual, were last and least. The wars had not gone well for them, and their castle was sad compared to those of the others. The image they carved was
