Loghru is the second planet orbiting the star of the Honoghr system. A scorching, irradiated wasteland, its surface is inhospitable to all but the hardiest forms of life. Tidal forces from Loghru's rapid and highly eccentric orbit drive frequent tectonic movements and volcanic flows within its silicate crust. A faint layer of sulfur dioxide expelled by this volcanic activity forms the planet's exosphere, which is not dense enough to be categorized as an atmosphere.

Some measure of reprieve from Loghru's harsh environment can be found at the poles, in the shadows of deep craters, and in the cavernous grooves cut by ancient quakes. Loghru's crust holds mining potential, and the aforementioned locations have been singled out by explorers as the most suitable for the required population centres. Even so, the planet's extreme conditions are likely to attract none but the brave and the desperate, as the residents of the existing outposts can attest.

Despite its environmental hostility, Loghru holds special meaning to the Noghri, the Honoghr system's native species, as a physical embodiment of the mythological figure for which it is named. The word "Loghru" is related to the Noghri word for "gleam", and the planet appears as one of the brightest and fastest-moving objects in the night sky over Honoghr. In the native mythology, Loghru is the twin brother of Ungr and a complicated, two-faced spirit, strongly associated with both violence and conciliation. His purview includes metal ("that which gleams"), freshwater bodies, daytime, and messengers. Since the revelation of Loghru's planetary properties by spacers, the Noghri have additionally come to associate him with fire, in both the warmth of a dukha's hearth and the rage of a burning forest.
