Native name for the Klingon homeworld, a planet of the star Klingon and the site of the Imperial Empire's capital First City. It is sometimes standardized as "Kronos."
It includes a lone huge land mass with a vast ocean, a severely tilted axis that causes wild seasonal changes, a turbulent atmosphere and extremes of both warm and frigid weather.
The capital city remains neutral to both sides during the empire's civil war, and even houses Sela and Movar.
