The Diollans were a species of sentient, featherless ornithoids that originated on the planet Dioll, in the Juvex sector. They were short and stocky, with broad beaks, leathery, mottled brown skin, and small intense eyes. Their sense of smell was sensitive enough to find Rodian pheromones repulsive. They were also masters of unarmed combat. Some Diollans served the local aristocratic Juvex House, while others opted to live elsewhere in the galaxy. The Nar Shaddaa-based bounty hunter Spurch "Warhog" Goa was a Diollan.
