The Hutt Gambit
In the distant past the desert worlds largest moon was hit by a rogue comet, sending out a massive debris field, which hammered the surface into ruin before settling into a ring of orbiting rock. This event killed off more than 99% of Geonosis’s native species.
Over millions of years, the few creatures who survived the devastation slowly reclaimed the planet. Random meteor impacts constantly weeded out the weaker species, leaving only the truly cunning, hardy, and ruthless species alive. The Geonosians, the dominant life form on the planet, constituted all three.
Geonosis has a large diameter but light gravity and dense atmosphere. Due to its weak magnetic field, harsh solar radiation storms and massive sandstorms are common occurrence on the planet. The planet consist of a diminutive molten core with a rocky mantle forming a rocky, desert world subject to flash floods that carve great highland canyons. Water makes up 5% of the surface.
Much of the planet’s architecture is similar in appearance to termite mounds, consisting of domes and buildings built into caverns and rock spires. Therefore, one could easily mistake Geonosian buildings for natural formations and the planet to be uninhabited.
