tahsekva

Tahsekva is a fictional celestial body featured in the science fiction works of author C. J. Cherryh. It is primarily known as the homeworld of the Pyanfar, a prominent alien species in her Foreigner series. The planet is described as having a harsh, arid environment with a binary star system that influences its climate and diurnal cycles. The Pyanfar have adapted to these conditions, developing a culture and physiology suited to their challenging homeworld.

The specifics of tahsekva's geography and atmosphere are often presented as context for the Pyanfar's behavior and societal structures. The intense radiation from its twin suns and the scarcity of water are key environmental factors that have shaped their evolution. This has led to the development of advanced technologies for survival, including sophisticated terraforming and life support systems, as well as a deeply ingrained sense of resourcefulness and resilience within their society.

The planet's name itself, tahsekva, is part of the Pyanfar language and reflects their connection to their home. While the exact linguistic meaning might not be fully detailed, it is presented as a significant identifier for the species and their origin. The Pyanfar's isolation on tahsekva has also contributed to their unique cultural development and their initial apprehension towards off-world contact, particularly with humans. The planet serves as a crucial element in understanding the Pyanfar's worldview and their interactions with other species in Cherryh's universe.
