There was substance indeed. And flavour as well. Yes, even his palate was deceived.

Jav watched him, smiling, as he ate.

“Is it not entirely satisfying?” he asked.

“I must admit that it is,” replied Carthoris. “But tell me, how does Tario live, and the other etherealists who maintain that food is unnecessary?”

Jav scratched his head.

“That is a question we often discuss,” he replied. “It is the strongest evidence we have of the non-existence of the etherealists; but who may know other than Komal?”

“Who is Komal?” asked Carthoris. “I heard your jeddak speak of him.”

Jav bent low toward the ear of the Heliumite, looking fearfully about before he spoke.

“Komal is the essence,” he whispered. “Even the etherealists admit that mind itself must have substance in order to transmit to imaginings the appearance of substance. For if there really was no such thing as substance it could not be suggested—what never has been cannot be imagined. Do you follow me?”

“I am groping,” replied Carthoris dryly.

“So the essence must be substance,” continued Jav. “Komal is the essence of the All, as it were. He is maintained by substance. He eats. He eats the real. To be explicit, he eats the realists. That is Tario’s work.

“He says that inasmuch as we maintain that we alone are real we should, to be consistent, admit that we alone are proper food for Komal. Sometimes, as to-day, we find other food for him. He is very fond of Torquasians.”

“And Komal is a man?” asked Carthoris.

“He is All, I told you,” replied Jav. “I know not how to explain him in words that you will understand. He is the beginning and the end. All life emanates from Komal, since the substance which feeds the brain with imaginings radiates from the body of Komal.

“Should Komal cease to eat, all life upon Barsoom would cease to be. He cannot die, but he might cease to eat, and, thus, to radiate.”

“And he feeds upon the men and women of your belief?” cried Carthoris.

“Women!” exclaimed Jav. “There are no women in Lothar. The last of the Lotharian females perished ages since, upon that cruel and terrible journey across the muddy plains that fringed the half-dried seas, when the green hordes scourged us across the world to this our last hiding-place—our impregnable fortress of Lothar.

“Scarce twenty thousand men of all the countless millions of our race lived to reach Lothar. Among us were no women and no children. All these had perished by the way.

“As time went on, we, too, were dying and the race fast approaching extinction, when the Great Truth was revealed to us, that mind is all. Many more died before we perfected our powers, but at last we were able to defy death when we fully understood that death was merely a state of mind.

“Then came the creation of mind-people, or rather the materialization of imaginings. We first put these to practical use when the Torquasians discovered our retreat, and fortunate for us it was that it required ages of search upon their part before they found the single tiny entrance to the valley of Lothar.

“That day we threw our first bowmen against them. The intention was purely to frighten them away by the vast numbers of bowmen which we could muster upon our walls. All Lothar bristled with the bows and arrows of our ethereal host.

“But the Torquasians did not frighten. They are lower than the beasts—they know no fear.
