agent when we see it.”
“Well, really only other virgula and sublimula, which of course the humans have no way of fashioning.”
“Ah, but what of rogue lobes?”
The natural precipitation cycles brought infinite numbers of virgula and sublimula down from their habitats in the clouds to ground level. When separated from the tropospheric mind in this way, the components of the mind were programmed for apoptosis. But occasionally a colony of virgula and sublimula would fail to self-destruct, instead clumping together into a rogue lobe. Isolated from the parent mind, the lobes frequently went insane before eventually succumbing to environmental stresses. Sometimes, though, a lobe could live a surprisingly long time if it found the right conditions.
“Do you think local factors in the lake here might encourage lobe formations?”
“There’s one way to find out,” answered Chellapilla.
It took only another half hour of prowling the lakeshore, scrambling over slippery rocks and across pebbled strands, to discover a small lobe.
Thick intelligent slime latticed with various organic elements—pondweeds, zebra mussels, a disintegrating bird carcass—lay draped across a boulder, a mucosal sac with the processing power of a non-autonomous twenty-second-century AI. The slime was liquescently displaying its mad internal thoughts just as a mail cloud did: fractured images of the natural world, blazes of equations, shards of old human culture ante-Upflowering, elaborate mathematical constructions. A steady whisper of jagged sounds, a schizophrenic monologue, accompanied the display.
Pertinax stared horrified. “Uploading this fragment of chaos to the tropospheric mind would engender destabilizing waves of disinformation across the skies. The humans don’t even need to explode their balloons. Simply letting the mind automatically read the slime would be enough.”
“We can’t allow this to happen.”
“Let’s hurry back to the others.”
“You damned toothy ratdogs aren’t going anywhere.”
A squad of humans had come stealthily upon Pertinax and Chellapilla while their attentions were engaged by the lobe. With rifles leveled at their heads, the wardens had no recourse but to raise their hands in surrender.
Two men came to bind the wardens. The one dealing with Chellapilla twisted her arms cruelly behind her, causing her to squeal. Maddened by the sound, Pertinax broke free and hurled himself at one of the gun-bearers. But a rifle stock connected with his skull, and he knew only blackness.
When Pertinax awoke, night had fallen. He found himself with limbs bound, lying in a cage improvised from thick branches rammed deep into the soil and lashed together. He struggled to rise, and thus attracted the attentions of his fellow captives.
Similarly bound, Chellapilla squirmed across the grass to her mate. “Oh, Perty, I’m so glad you’re awake! We were afraid you had a concussion.”
“No, I’m fine. And you?”
“Just sore. Once you were knocked out, they didn’t really hurt me further.”
Sylvanus’s sad voice reached Pertinax as well. “Welcome back, my lad. We’re in a fine mess now, and it’s all my fault for underestimating the harmful intentions of these savages.”
Firelight flared up some meters away, accompanied by the roar of a human crowd. “Where are we?”
“We’re on the town green,” said Chellapilla. “The humans are celebrating their victory over us. They slaughtered our Kangemu and are roasting them for a feast.”
“Barbarians!”
Tanselle spoke. “Cimabue and I are here as well, Pertinax, but he did not escape so easily as you. They clubbed him viciously when he fought back. Now his breathing is erratic, and he won’t respond.”
“We have to do something!”
“But what?” inquired Sylvanus.
“The least we can do,” said Chellapilla, “is inform the tropospheric mind of our troubles and the threat from rogue lobe infection. Maybe the mind will know what to
