Yorbund: Regina/Spinward Marches, 2303, C7C6503-7, --, Ni Fl, G220, Im, M8-VI.
Yorbund is a non-industrial Imperial world located within the Kinorb Cluster in the Regina Subsector of the Spinward Marches. It has a warm climate and a corrosive fluorine atmosphere that has so far limited efforts to explore the planet -- the local atmosphere is insidious, corrosive, and will defeat all personal protective measures within hours. Thus, the surface of Yorbund is largely unexplored, with few individuals venturing far from the starport and associated caverns.
Cloaked in a densely overcast atmosphere, little is known of the surface features of the world. Sporadic low-level flights have revealed a geography of low, rolling hills, punctuated by volcanic vents releasing ash, lava, and sulfurous gases into the air, and carpeted with a wide variety of fungal vegetation in shades of gray.
As experience has shown, Yorbund is subject to seismic tremors, generally of low magnitude, but sometimes quite severe; such tremors have been detected from nearly all points on the world's surface. Finally, the planet is known to be subject to considerable volcanism.
The population is concentrated in a few underground cavern complexes. Yorbund's major resource is fungi grown in the caverns; it provides food, fibers, and fuel, and is exported as pharmaceuticals.
The Kinorb Cluster includes Heya (SM2404), Kinorb (SM2202), Tentus (SM2201), and Yorbund (SM2393).
