Jalarran existed as a planetary body within the Senex sector, situated in the Mid Rim region, and was classified as a planet.
The surface of Jalarren was dominated by a desert landscape, abundant with surface salts and subterranean minerals and metals. These resources were highly valued by numerous mining enterprises operating in that galactic region. The Senex Worlds based houses of Garonnin, Petro, and Picutorion each maintained mining presences on the planet, a situation that caused resentment among the indigenous Jalarri nomads, who generally dissolved any alliances with these houses. However, smaller tribal groups were sometimes contracted by competing house mining corporations to execute raids against their rivals' facilities.
When the external mining corporations first arrived on Jalarren, they faced the significant problem of securing their own water supply. The arid atmosphere, characterized by low humidity, rendered Moisture vaporators ineffective. Attempts to negotiate with the Jalarri for access to their water extraction methods proved unsuccessful, compelling the external entities to incur substantial expenses by importing water from the home systems of the Senex Houses.
