Low temperature xenosophonts inhabiting Titan-like worlds

An example of a Muuh adapted to heavier acceleration/gravity. Almost all Muuh are capable of functioning upside-down just as well as right-way up, although certain features of their internal anatomy show that their top and bottom sides are significantly different from each other. Muuh worlds are icy moons and planets with atmospheres rich in methane and coloured organic compounds (usually orange or pale green), and ethane seas.

The Muuh (a name given to them by an impatient Cygexpa communications officer) apparently evolved on a cold low-gravity Titan-like moon somewhere in the Cygnus direction of the Orion Arm. Their biochemistry is based on liquid hydrocarbons, in a methane-nitrogen atmosphere; it is one of the best known examples of methane-ethane based life.

Life on Muuh worlds, just as on the hypothetical Muuh home world, is based on the production of energy-rich compounds in the upper atmosphere, driven by solar radiation and the magnetic fields of the central planet — contrary to the arrangement on most life bearing worlds, plants are not a significant factor in the local biology. Instead, the primary producers are gatherer animals that collect the nutrients and in turn become prey for other animals. Some gatherers are sedentary, not unlike terrestrial corals or anemones or barnacles, while others are mobile. Various scavengers and saprophytes break down the remains, releasing methane into the atmosphere. The whole pace of life is extremely slow compared to Terragen life.

The Muuh are believed to have evolved from "rapid" mid-sized predator/omnivores; their ancestors would have filled an ecological niche like that of terrestrial raccoons. They are two-meter spider or crab-like creatures with a bark-like spiky exoskeleton that constantly grows (armor-carving is an important part of Muuh appearance and health). There are few external differences between the upper and lower sides; Muuh can simply flip between them with little trouble. Locomotion is through six legs where the front pair branches off a number of manipulator limbs. An ordinary Muuh moves at most one meter per second in a hurry, and most prefer to move much more slowly. Sensory organs, mainly echolocation and a heat sense were located around the rim of the shell. Muuh are hermaphrodites. As a rule they form lifelong pairs which repeatedly bear paired children. These marriage-pairs and sibling-pairs form the central social units of society.

Muuh are very resistant to extremes of cold, and can withstand being frozen solid for long periods of time. However, temperatures above -150 °C are lethal. "Freezing" of course refers to the temperature at which the methane-ethane mix that is their equivalent of water is no longer liquid. Water is a mineral in the Muuh environment, and for the Muuh water ice is a useful solid building material and is often used as part of their spaceships and habs.

Muuh that inhabit low-gravity planets and moons are often lighter in build than those which have colonised heavier worlds. Since their bark-like shell grows continuously, the Muuh trim and carve it into ornamental or symbolic shapes, often humorous. Each member of a pair trims the other's bark, carving messages into their ventral and dorsal surfaces that can be read by touch.

Intellectually the Muuh are slow but not stupid thinkers, with excellent long-term memories. If they moved and thought at typical Terragen speeds they would likely be viewed as nearly hyperactive romantics. They are highly imaginative and often prefer fiction and ingenious stories to real life. They devote a great deal of time and effort to creating art, virtual worlds, role-playing scenarios and fantasies in great detail. This has somewhat hampered their technological development, as the strict procedures necessary for science do not appeal to their mindset; instead they tend to prefer inspired experimentation. The reliance on inspiration has made them dependent on their occasional geniuses or correct madmen, who receive further respect and support for their few viable innovations even though 99% of all the ideas they generate don't work out.

Muuh society is variable between different worlds, but tends to be based on inherited status augmented by an elaborate system of advisers/challengers who force the leaders to clarify their decisions. There is a great deal of leeway in how decisions are implemented or obeyed, making their society hard for outsiders to get into. Mutual obligations, gifts and persuasion are important factors in getting anything done.

Muuh civilization is extremely old and slow. It is uncertain how long it took to achieve spaceflight, but over the span of many millions of years they expanded across a sizable volume, colonizing other Titan-like planets or building vast orbital habitats. They made contact with a number of xenosophont races, as well as creating and provolving a number of indigenous species. At least one of these, the Soft Ones, became a major interstellar species in their own right. Contact was usually peaceful, as Muuh interests seldom collided with others, and they have provided Terragens with invaluable second-hand information on a number of undiscovered or extinct species. The main exception to the peaceful encounters was the discovery of a destructive civilization, now believed to be an artificial remnant of some other species (some have suggested an autonomous weapon system such as the Dawn Hunters but this remains debatable) that began to systematically attack the Muuh 14.8 million years ago. The Muuh were too slow in reacting to the fast and advanced enemy. They mobilized a desperate and powerful defense of the home worlds that they knew was doomed, but at the same time they sent out long-range colony ships to remote systems in order to save their race. It is unknown what happened to the original Muuh Empire, but it is generally assumed to have been destroyed.

The first Muuh polities encountered by Terragens exist within a volume between Cygnus OB4 and the Cygnus Dark Nebula, and appear to be descended from a single surviving colony ship. The Muuh settlements in this region constitute a local empire around 100 light years across. They were discovered by a Cygexpa probe in 7854 AT, and after 400 years of slow (to humans) initial contact a wormhole link was set up in 8266 to the closest Muuh system (CEA-346746 / Muuhome). It is not known if other Terragens had previously encountered the Muuh, but the possibility of contact by a relativist isolationist ai clade cannot be excluded.

Since the initial discovery many more Muuh colonies have been encountered in a large and sparsely settled volume of space to rimward of the Terragen Sphere; this is presumably the remnant of the old Muuh Empire. A border zone has been established in this region, centered on the Pluton Volume; many cold-loving Terragen clades have migrated there, as well as representatives of the race of Soft Ones known as the Epp. As is well known, the region was devastated during the so-called Epp War, which was the first time that the Muuh revealed their ancient System of Response defenses.

The Muuh do not consider sub-relativistic journeys to be slow, especially since they tend to freeze themselves during the trip and things do not change much between departure and arrival anyway. Their technology is largely cryobiological, based on low-temperature life feeding on Titan-like or Kuiper-belt environments and growing the necessary structures out of polymers, ice and frozen gas.

Muuh and To'ul'hs have some similarities despite their tremendously different biochemistries. Both come from dark worlds where nutrients descend from above, and both employ echolocation and other non-visual senses. This has given them somewhat similar basic view of reality, making it easier for them to understand each other than humans and most other Terragens. It appears the Muuh regard humans and their offspring as yet another hotheaded Inner System species-complex with more energy than style, although some Muuh informants say they have to hand it to the Terragens that they have some useful technology and original perspectives. Trade exchange has been profitable for both groups, although it is clear that the Muuh are not interested in becoming part of any Terragen political organisation, despite some of them having worked closely with the Archailects during the Epp War.

In some ways, the old and sparsely populated Muuh volume is a barrier to further Terragen expansion in the Rimward direction; the Muuh only use a fraction of the resources of the stars in that volume, and negotiations are proceeding to allow Terragen colonists access to some of the unused planets and stars. This initiative has met with limited success to date.
