Generic term for alien (non-terragen) lifeform. May be animal-like, plant-like, protistan, exotic chemistry, or any other possibility. Does not have to be sophont. In fact, just as on Earth, very few alien species ever evolve any measure of cognitive intelligence.
While some display broadly parallel evolutionary traits with terrestrial creatures, others are completely unlike any Terragen life. May be found in any environment that can support life, include extremophile conditions deadly to most terragen organisms. The number of different xenobiont species discovered and recorded so far numbers in the trillions, but this is still but a tiny percentage of total species of life-forms to be found in our galaxy alone. Also, even planets that have been mapped and surveyed may contain many undiscovered or unrecognized species (especially rare or microscopic forms).
Many natural garden worlds with their complements of alien life forms have been claimed by corporations or caretaker gods, the former marketing select species as pets or novelty value, the latter jealously guarding the indigenous biota from appropriation by other sentients.
Ho'th'hss'lho University - Text by M. Alan Kazlev Located on Morogai (also called Ho'th'lhu'ooht), Ho'th'hss'lho University is an important nexus of post-To'u'l and posthuman education. It is based around the Power Ho'th'hss'lho.
Muuhian Epoch - Text by M. Alan Kazlev Local (Perseus-Outer Orion) historical epoch characterized by the Muuhian interstellar civilization; 1.2 to 0.6 mya. Approximately equivalent in time to the middle Pleistocene of Old Earth. The Muuhian Epoch was followed (after a long period of time) by the Auldlimnerian Epoch.
To'ul'ho'lo'ss - Text by Stephen Inniss, after the original by Anders Sandberg To'ul'h language of ancient origin, traditionally used in record keeping and for intercultural and international communication. A pidgin version is used among their various post-to'ul'h clades and with humans or other xenosophonts.
To'ul'human - Text by Steve Bowers Homorph To'ul'h who have been given or adopted human shape by advanced biotech. They also can take To'ul'h form in earthlike environments or adapted human form in toulovenusian environments.
Xenobiologist - Text by M. Alan Kazlev One who studies non-terragen lifeforms. Most survey and research vessels have at least one Xenobiologist (or equivalent turing- or superturingrade ai or expert system) on board. While some xenobiologists have a generic knowledge that is applied to xenobiota and xenecologies in general, most tend to specialize in an individual world, specific environment or world type, or even a single alien taxon or species.
Xenobiota - Text by M. Alan Kazlev The totality of non-terragen life on a specific planet or non-terragen ecosystem.
Xenologist - Text by M. Alan Kazlev, based on the original by Robert J. Hall One who studies non-terragen life-forms, especially sophont non-terragens. Xenologists are responsible for devising first contact procedures and frequently serve in the role of adviser to an alien emissary or contact intelligence. Xenology is a popular and glamorous profession, but the number of aspirants for professional xenologist outweigh by several orders of magnitude the actual vacancies available.
