Ayirn

Ayirn is a warm temperate planet located in Federation space, and is the site of a Orion colony.

Despite the planet's close proximity to both the Klingon Empire and Orion space, Ayirn, with its Orion administration, is a completely loyal member of the Federation. Due to its location, the planet is of immense strategic value to Starfleet. In addition, the six Voltab brothers and their families, who are the dominant rulers of the planet, seem quite capable of keeping Ayirn tidy, orderly, and productive.

Nevertheless, Federation documents exist which claim that Ayirn, or at least some of its inhabitants, trade arms to anti-Klingon resistance movements on other Orion colonies dominated by the Klingon Empire. Thankfully, aside from a mild diplomatic protest, the Klingons have ignored the problem. Ayirn is not part of the Organian Peace Treaty imposed upon the Federation and Klingon Empire, and as a result, could be a target for Klingon preemptive raid. (The Orions: Book of Common Knowledge)
