During the time they called their twentieth century there was a whole series of wars, not such little quarrels as we have so often between our city-states, nor even such as that between the Memphis League and the Empire, five years ago. Their wars spread like storm clouds around the world, and were fought between millions of men with unimaginable weapons that flung destruction a hundred miles, and with ships on the seas, and with gases."

"What's gases?" asked Hull.

Old Einar waved his hand so that the wind of it brushed the youth's brown cheek. "Air is a gas," he said. "They knew how to poison the air so that all who breathed it died. And they fought with diseases, and legend says that they fought also in the air with wings, but that is only legend."

"Diseases!" said Hull. "Diseases are the breath of Devils, and if they controlled Devils they used sorcery, and therefore they knew magic."

"There is no magic," reiterated the old man. "I do not know how they fought each other with diseases, but Martin Sair of N'Orleans knows. That was his study, not mine, but I know there was no magic in it." He resumed his tale. "So these great fierce nations flung themselves against each other, for war meant more to them than to us. With us it is something of a rough, joyous, dangerous game, but to them it was a passion. They fought for any reason, or for none at all save the love of fighting."

"I love fighting," said Hull.

"Yes, but would you love it if it meant simply the destroying of thousands of men beyond the horizon? Men you were never to see?"

"No. War should be man to man, or at least no farther than the carry of a rifle ball."

"True. Well, some time near the end of their twentieth century, the ancient world exploded into war like a powder horn in a fire. They say every nation fought, and battles surged back and forth across seas and continents. It was not only nation against nation, but race against race, black and white and yellow and red, all embroiled in a titanic struggle."
