Elnacons originated from Nacon, a planet with an atmosphere abundant in ammonia; they were a tall and serene sentient species. Due to their native world's environment, they needed specialized breathing apparatus when venturing elsewhere. Their physical features included noseless faces and hands with four fingers. Despite their imposing stature and power, which sometimes led to their misidentification as ruffians, Elnacons were generally peace-loving and deeply valued family ties. A notable Elnacon was Dava Cassamam, a cloud-miner working on gas giant planets, who also enjoyed playing sabacc.
