Ayirn was the third planet in the Symbokovech star system located in the Spinward Horn of Federation space, in the Alpha or Beta Quadrant. It had a single moon and was the only class M planet in its system. It was the site of an Orion Colony, but was also a member of the Federation.
The Voltab family, of six brothers and their respective families, governed the planet and kept Ayirn stable, peaceful, and productive during the late 23rd century. Despite the planet's close proximity to both the Klingon Empire and the Orion Neutrality Area, and its completely Orion administration, Ayirn was a loyal Federation member. Due to this and its strategic location within the Spinward Horn, of which it was the foremost world, the planet was of immense value to Starfleet.
Nevertheless, Federation documents existed which claimed that Ayirn, or at least some of its inhabitants, traded arms to anti-Klingon resistance movements in Orion Colonies dominated by the Klingon Empire. Thankfully, aside from a mild diplomatic protest, the Klingons ignored the problem. Ayirn was not part of the Organian Peace Treaty imposed upon the Federation and the Klingon Empire, and as a result, it was a potential target for a Klingon preemptive raid.
It had a total surface area of 176,714,580 square kilometers and, with 38% land mass, a total land area of 67,151,540 square kilometers. About 43% of Ayirn's makeup was normal metals, 17% was radioactive elements, 6% was industrial crystals, and it had trace amounts of gemstones and other special minerals. It had a warm temperate climate, a thin class M atmosphere and an 18-hour-long day.
It had a technological/sociopolitical index of 999974-74 and a planetary trade profile of CBCDBCD/A(B). (FASA RPG - The Orions module: Book of Common Knowledge)
