"How is that?" Conan inquired uneasily; this savored too strongly of sorcery for comfort.

"Much of the time these people lie in sleep. Their dream-life is as important — and to them as real — as their waking life. You have heard of the black lotus? In certain pits of the city it grows. Through the ages they have cultivated it, until, instead of death, its juice induces dreams, gorgeous and fantastic. In these dreams they spend most of their time. Their lives are vague, erratic, and without plan. They dream, they wake, drink, love, eat and dream again. They seldom finish anything they begin, but leave it half completed and sink back again into the slumber of the black lotus. That meal you found — doubtless one awoke, felt the urge of hunger, prepared the meal for himself, then forgot about it and wandered away to dream again."

"Where do they get their food?" interrupted Conan. "I saw no fields or vineyards outside the city. Have they orchards and cattle-pens within the walls?"

She shook her head. "They manufacture their own food out of the primal elements. They are wonderful scientists, when they are not drugged with their dream-flower. Their ancestors were mental giants, who built this marvelous city in the desert, and though the race became slaves to their curious passions, some of their wonderful knowledge still remains. Have you wondered about these lights? They are jewels, fused with radium. You rub them with your thumb to make them glow, and rub them again, the opposite way, to extinguish them. That is but a single example of their science. But much they have forgotten. They take little interest in waking life, choosing to lie most of the time in death-like sleep."

"Then the dead man at the gate—" began Conan.

"Was doubtless slumbering. Sleepers of the lotus are like the dead. Animation is apparently suspended. It is impossible to detect the slightest sign of life. The spirit has left the body and is roaming at will through other, exotic worlds. The man at the gate was a good example of the irresponsibility of these people's lives. He was guarding the gate, where custom decrees a watch be kept, though no enemy has ever advanced across the desert. In other parts of the city you would find other guards, generally sleeping as soundly as the man at the gate."
