In the northernmost geyland of Ashlesa live the Polar Piglets. The 35 cm long, waddling creatures are highly social in nature, spending as much time as possible in close proximity to several other individuals.

They mineral-rich water flowing up from below forms large, bulging rocks wherever vents open to the surface. These rocks are filled with microfauna — there being no true “plants” on Ashlesa — that eat the inside of the rocks, expanding colonially and through the underground streams and rivers. They’re the primary food of the polar piglets, who look for the rare tiny holes in the rocks where the microfauna dig too far. When they see such a hole, they waddle up to it and insert their 20 cm prehensile radula, rasping the microfauna off the interior walls of the hollow rock.

Once the piglet has been satisfied, it stops completely digesting its food, forming it into little balls in a crop and mixing it with packets of its own genetic material.

When a piglet sees another up against a rock, it will amble up and attach itself by its soft mouth to the cloaca of the grazing individual. It will stimulate the grazing individual with its radula, receiving the balls of semi-digested food and genetic material. Chains are made this way as much as four individuals long, each receiving the passed-up food and genetic material of all the individuals ahead of it. Past four, there is little nutrition and the genes are too jumbled to be much use. The last in line lays eggs of all the combinations of genetic material, with each individual’s material being combined with the material of each and every of those behind it in all possible ways.

Consumptive and procreative purposes aside, the piglets spend much of their time so attached. They travel around in chains of two or three, and when groups meet another, they’ll often form rings and knots in an ecstatic, wiggling, chirping pile.

When humans first orbited Ashlesa 5.2 (the second moon in orbit around the fifth “planet” — itself a brown dwarf — orbiting the star Ashlesa) , they were struck by its geology. A single vast plain, desert-like, with the occasional oasis dotting the landscape, broken only by chains of geysers, some thousands of miles across. Subterranean rivers ran under the hard crust, emerging only rarely. Life flourished both outside and in the geyser chains, but they seemed completely distinct. Not only was life in one of the “geylands” (as the explorers called them) different from that outside, it was distinct from every other geyland. They were each an entire closed ecosystem, biochemically (and in one case, physically) separated from the rest of the planet.

A team landing near the equator were met by titanic, 8-limbed, starfish-like creatures, slowly walking in a widely separated herd. Each “foot” was an obviously sensitive organ, feeling along, apparently sniffing and grazing on the thin scum that covers much of the broad plain. Its limbs were dotted with small, black, featureless eyes, largely facing up. The creatures, “Octoforms” as the explorers called them, completely ignored the human explorers.

Landing near the Boreal geyland, the explorers discovered 40 cm wide,  three-limbed creatures they called “triforms” happily grazing on some sort of biochemical sludge at the edges of the glacier. While observing them, the explorers were startled when a harpoon shot from the sky and speared one, followed by a crack like a gunshot. Floating silently in the air above the triforms, its shadow cast to the north of its prey, hovered a balloon. Five arms reached out and hugged the envelope. A small cloud of steam drifted away on the wind. The remains of the triform’s small herd had galloped away, turning like wheels, scattering like birds. The speared one struggled for mere seconds before it went completely slack.

The harpoon remained embedded in the creature and the ice below it for several minutes while the surveyors noticed that they prey was becoming a dry husk. After a half hour, there was so little of the creature that, when the zoölogists approached later, there was nothing but a dry skin on the ground.

The balloon had retracted its harpoon and was drifting away slowly, directing its flight subtly with small barks of fire from the appendage from which it had fired its harpoon. It drifted up and away until its form was no longer distinct. “It’s like lightning that wants to hit you,” said one awed researcher.

A boreal triform was discovered, partially eaten by some other animal. The team lost no time in dissecting the fresh specimen. It is completely symmetrical, each limb being a complete copy of the others. It is covered in a thick skin that responds to electrical pulses, itself a fine muscle. Underneath the skin are many thick bands of heavier muscle tissue, supported by a fibrous, almost plastic quill running the length of each limb. This particular species has soft, fine “fingers” along each limb, each with a small orifice.

At the base of each limb are what appear to be several clusters of nerve-like fibers. Experiments with living triforms — and indeed, every other planar form of life on Ashlesa — shows that the distal nerve clusters control reflexes and autonomic activity of the limb. The most proximal body, on the other hand, seems to be involved in communication with the other limbs. With their simple eyes, this is the only way the creatures can assemble complex vision. As it is the largest nervous body, this is apparently a challenging task.
