"It might have been—if that's really what happened," Jason said. "But I think you have the problem turned backwards. It's a war between native Pyrran life and humans, each fighting to destroy the other. The life forms change continually, seeking that final destruction of the invader."

"Your theory is even wilder than mine," Rhes said. "That's not true at all. I admit that life isn't too easy on this planet ... if what I have read in the books about other planets is true ... but it doesn't change. You have to be fast on your feet and keep your eyes open for anything bigger than you, but you can survive. Anyway, it doesn't really matter why. The junkmen always look for trouble and I'm happy to see that they have enough."

Jason didn't try to press the point. The effort of forcing Rhes to change his basic attitudes wasn't worth it—even if possible. He hadn't succeeded in convincing anyone in the city of the lethal mutations even when they could observe all the facts. Rhes could still supply information though.

"I suppose it's not important who started the battle," Jason said for the other man's benefit, not meaning a word of it, "but you'll have to agree that the city people are permanently at war with all the local life. Your people, though, have managed to befriend at least two species that I have seen. Do you have any idea how this was done?"

"Naxa will be here in a minute," Rhes said, pointing to the door, "as soon as he's taken care of the animals. Ask him. He's the best talker we have."

"Talker?" Jason asked. "I had the opposite idea about him. He didn't talk much, and what he did say was, well ... a little hard to understand at times."

"Not that kind of talking." Rhes broke in impatiently. "The talkers look after the animals. They train the dogs and doryms, and the better ones like Naxa are always trying to work with other beasts. They dress crudely, but they have to. I've heard them say that the animals don't like chemicals, metal or tanned leather, so they wear untanned furs for the most part. But don't let the dirt fool you, it has nothing to do with his intelligence."

"Doryms? Are those your carrying beasts—the kind we rode coming here?"

Rhes nodded. "Doryms are more than pack animals, they're really a little bit of everything. The large males pull the ploughs and other machines, while the younger animals are used for meat. If you want to know more, ask Naxa, you'll find him in the barn."
