He knew the barren deserts of the south, the wastes of red dust, the dead sea bottoms—the terrible thirst of Mars, growing greater with every year of the million that had passed since Ban Cruach locked the Gates of Death.

He knew the canals, the pitiful waterways that were all that stood between the people of Mars and extinction. He remembered the yearly release from death when the spring thaw brought the water rushing down from the north.

He thought of these cold creatures going forth, building again their great towers of stone, sheathing half a world in ice that would never melt. He thought of the people of Jekkara and Valkis and Barrakesh, of the countless cities of the south, watching for the flood that did not come, and falling at last to mingle their bodies with the blowing dust.

He said again, "No. Never."

The distant thought-voice of the seven spoke, and this time the question was addressed to Ciara.

Stark saw her face. She did not know the Mars he knew, but she had memories of her own—the mountain-valleys of Mekh, the moors, the snowy gorges. She looked at the shining ones in their high seats, and said,

"If I take that sword, it will be to use it against you as Ban Cruach did!"

Stark knew that the seven had understood the thought behind her words. He felt that they were amused.

"The secret of that sword was lost a million years ago, the day Ban Cruach died. Neither you nor anyone now knows how to use it as he did. But the sword's radiations of warmth still lock us here.

"We cannot approach that sword, for its vibrations of heat slay us if we do. But you warm-bodied ones can approach it. And you will do so, and take it from its place. One of you will take it!"
