Those looking to trade with Geonosis would often provide exotic predators for the arena entertainment as payment. Such creatures included acklays, nexus, reeks, and mongworsts. The arena itself was a natural formation carved out by millennia of weathering, with additions made by the Geonosians. Its floor consisted of sand and silt upon which events took place. The lower walls of the arena base included ancient low-relief carvings depicting famous battles and events. The arena could also be flooded for aquatic events.
