The entire constellation is under strict quarantine due to the dangers inherent in human-Majat interaction. The first contact with the Majat, for example, resulted in the human delegation being eaten. Humans do live in the Hydri stars, however, because Union had established colonies there before ceding Serpent's Reach to the Alliance, which subsequently imposed the quarantine. A space station orbiting the planet Beta Hydri II, called Istra, serves as the sole point of contact between the Alliance and the human/Majat society of the Hydri stars.
