Book om ett "fräckt land" som patrulleras av monster - omger en teleport, grön sjukdom

Det här är romanen För att erövra kaos av John Brunner .

Askanvändaren kallas Conrad:

Grey from head to foot with wood-ash, Conrad sat by the soap-vats, in one hand his knife held by the blade close up near the point, in the other a piece of excellent soap—the hardest and whitest he had ever seen set in the shallow wooden pans.

Det orena landet kallas faktiskt barrenland , och monster vandrar verkligen ut av det:

The barrenland lay on the face of the world like an ulcer, nearly round, more than three hundred miles in circumference. It had been there so long that it was accepted; it was there and it was a fact and it was.
...
The price of living there was the necessity of contending with the things that every so often wandered out of the barrenland and killed.

Sjukdomen är grön mögel inte grön ague . Det infekterar först en karaktär som kallas Ampier, och kommer från en bit av en främmande beast från barrenlands.

Yanderman ignored the question. He said curtly, “Ampier died in the night—did you know?”
“Of course. I was informed directly it happened; I’d given instructions.”
“Have you seen the body?”
“No.”
Yanderman shuddered. “I saw it. They were carrying it out for burning as I came by. He looked as though he’d simply rotted to death. He was completely covered in that filthy green mould.”
Duke Paul nodded. “So they told me. Obviously the beak of the thing he killed was infected, and poisoned his wound. The medics said they could find nothing that would stop the mould growing without killing the sufferer

Berättelsen handlar om en expedition ledd av Jervis Yanderman för att undersöka de barrenlandsna, så Conrad går inte bara dit ensam - han kommer dit som en del av en expedition.

I mitten av barrenlands är:

The Station. It is indeed an instellar portal, but the people living there don't know how it operates. Conrad manages, quite by accident, to reactivate the portal and regain contact with the rest of galaxy.
