That having been said...Tiran'Dira is an earth class planet orbiting an ordinary G type star. It's a bit warmer than earth, the oceans are slightly smaller, and the water is more widely spread over the surface. Tiran'Dira has only one desert of any noteable size. The land area is divided into 8 continents, the largest being about the size of North America, and thousands of islands ranging from the very large to the extremely small. Slightly over half of the planet's land surface is covered by rainforest, with the remainder being divided into forest and grasslands, taiga and a relatively small areas of tundra at the poles. Tiran'Dira's grasslands are found in areas which in Earth's climate would be deserts...its single desert is found on the northern border of the grassland described in this story. Mountain ranges abound on the planet, with geological activity being slightly higher than on earth. A good number of the islands are volcanic. There are no active volcanoes in the region of the compound in this story--that mountain range most closely resembles the Rocky Mountains, and is the result of tectonic activity.
In terms of Pern, (Anne McCaffrey's creation), this story is set in the future, and Pern has been rediscovered by the homeworld (all such should be considered "alternative universe" fiction, and in no way implies any toe-trodding in her reality). The expanding human race finally encountered a species which was actively hostile. The Marsx, a species which most closely resemble an Earth marsupial called the quoll, turned out to be highly territorial. They took immediate offense to human encroachment into their region of space, and saw in humans a threat to their freedom of expansion.
The beginning of the war with the Marsx was what had originally cut Pern (all rights reserved by A.McCaffrey and whatnot) off from contact, and it destroyed the human government of the time. In spite of this, the humans won the war, and the Marsx were viciously driven back into their home system, colonies destroyed. The Marsx are now themselves an endangered species, numbering only a mere 5000 individuals which are believed to still inhabit their home world.
Humans reestablished communications and a government in the form of a loosely governed confederation of planets. The confederation consisted of all known human colonies, and those alien colonies and homeworlds which expressed an interest in joining. A few alien species declined this invitation, being standoffish in all of their affairs. The confederation regards all tool-using sentient species to be granted the status of citizens (or in the case of the more standoffish species, treaty partners). Non tool-using sentients are recognized and given similar basic rights, but they do not have the right to vote, own property (save for land or other territories), or represent themselves in legal situations. In some ways they are legally treated as chattel, but they do have more rights than, say, pre-liberation Earth women or human children. A second class of beings, labeled semi-sentient, are treated like true chattel. Semi-sentient beings are those which range from a level slightly above that of a very bright chimpanzee to just under the level of the lowest end of the normal human intelligence range.
Of all the confederated species, humans do stand out in one regard. While they may not have the highest technological or sociological level, they do have the most intensive, thorough, and skillful technology and knowledge of genetics and genetic engineering. As a result, non tool-using (and even tool-using) sentients and semi-sentients which find themselves in trouble have been known to appeal to human scientists for help in rescuing their species.
When Pern (c. A. McCaffrey, yadda yadda) was rediscovered, its primary wishes to be left in peace were honored. There was, however, an exception. Confederation environmental regulations prohibit extinctions of species which are the direct cause of sentient actions. As a result, some Pernese animals were considered to be imperiled. While the Pernese dragons were labeled semi-sentient, and considered to be in good hands, their numbers were small, and there was evidence to suggest that they may dwindle further in the absence of the threat from the Red Star. The Pernese firelizards presented a different dilemma. The true firelizards had been genetically altered early on in the human colonization of pern. They had proliferated across the planet, and had nearly replaced the native dragonets. The dragonets were considered to be an endangered species.
Once confederation scientists had found the key to impressing both dragonets and Pernese dragons (the candidate simply had to be psi-active), volunteers were sent to Pern to impress several of the creatures and take them off planet to establish breeding programs elsewhere. Due to the enormous size of the dragons, no single planetary ecosystem could be expected to support a great number of them. Although they were artifically created, their semi-sentient status insured that they would be rescued from their plight, and the puzzle of their decreasing fertility would be solved via genetic engineering, so that their species could maintain stable populations.
The dragonets were easier--small, pleasant creatures which could bond so readily and completely to their owners, they were considered tremendous pets. But before they could be proliferated across the confederation, they first had to be stabilized as a population. (All Pern stuff c. Anne McCaffrey and all that).
Tiran'Dira, being in a rather remote system, was the ideal place to work on both of these projects. Free from high population areas which might attract individuals interested in exploiting the endangered and threatened species, its climate was friendly to a wide variety of life forms. The needs of its own species capped the deal, and Tiran'Dira became the center for the confederation's most important breeding and genetic engineering projects.
