Nalydians were humanoid beings with small statures and brown skin, originating from the planet called Nalyd. As of 138 ABY, these species had built a civilization on their homeworld, characterized by stony mesas and pinnacles, all shrouded in a swirling orange fog. Furthermore, they managed to domesticate a spider-like species. Notably, they practiced public executions in arenas for offenses like murder, assault, and the disruption of public transportation. A known individual from this species was the criminal Dieben, who, after the Carreras Incident, was sent back to Nalyd to be executed for his numerous crimes.
