Its yellow eyes flickered to the knife in his hand. He dropped the knife in the grass and walked forward, unarmed, wanting the prowler to know that he understood; that for them in that moment the gulf of two hundred and fifty light-years did not exist.

He stopped near it and squatted in the grass to begin binding up his broken arm so the bones would not grate together. It watched him, then it began to lick at its bloody shoulder; standing so close to him that he could have reached out and touched it.

Again he felt the sense of wonder. They were alone together in the glade, he and a prowler, each caring for his hurts. There was a bond between them that for a little while made them like brothers. There was a bridge for a little while across the gulf that had never been bridged before....

When he had finished with his arm and the prowler had lessened the bleeding of its shoulder it took a step back toward the ridge. He stood up, knowing it was going to leave.

"I suppose the score is even now," he said to it, "and [p. 120] we'll never see each other again. So good hunting—and thanks."

It made a sound in its throat; a queer sound that was neither bark nor growl, and he had the feeling it was trying to tell him something. Then it turned and was gone like a black shadow across the grass and he was alone again.

He picked up his knife and bow and began the long, painful journey back to the caves, looking again and again at the ridge behind him and thinking: They have a code of ethics. They fight for their survival—but they pay their debts.

Ragnarok was big enough for both men and prowlers. They could live together in friendship as men and dogs of Earth lived together. It might take a long time to win the trust of the prowlers but surely it could be done.

He came to the rocky trail that led to the caves and there he took a last look at the ridge behind him; feeling a poignant sense of loss and wondering if he would ever see the prowler again or ever again know the strange, wild companionship he had known that day.

Perhaps he never would ... but the time would come on Ragnarok when children would play in the grass with prowler pups and the time would come when men and prowlers, side by side, would face the Gerns.
