“It is the same,” agreed the knight, his voice heavy with regret. “I suppose it is fortunate we have not yet signed on, though I doubt they will see what we do as being purely a matter of defence.”

“They do not know what they harbor here,” said Fitz.

“It is a pleasant city.” said Hereward, taking up his cup again to take a large gulp of the slightly sweet wine. “In a pretty valley. I had thought I could grow more than accustomed to Shûme—and its people.”

“The bounty of Shûme, all its burgeoning crops, its healthy stock and people, is an unintended result of their godlet’s predation upon the surrounding lands,” said Fitz. “Pralqornrah is one of the class of cross-dimensional parasites that is most dangerous. Unchecked, in time it will suck the vital essence out of all the land beyond its immediate demesne. The deserts of Balkash are the work of a similar being, over six millennia. This one has only been embedded here for two hundred years—you have seen the results beyond this valley.”

“Six millennia is a long time,” said Hereward, taking yet another gulp. The wine was strong as well as sweet, and he felt the need of it. “A desert might arise in that time without the interference of the gods.”

“It is not just the fields and the river that Pralqornrah feeds upon,” said Fitz. “The people outside this valley suffer too. Babes unborn, strong men and women declining before their prime . . . this godlet slowly sucks the essence from all life.”

“They could leave,” said Hereward. The wine was making him feel both sleepy and mulish. “I expect many have already left to seek better lands. The rest could be resettled, the lands left uninhabited to feed the godlet. Shûme could continue as an oasis. What if another desert grows around it? They occur in nature, do they not?”
