Like the Luxans, Ilanics possess cranial tentacles, called "tenkas:" two large ones on their forehead, and two mid-sized ones towards the back of the skull. Males also have secondary tenkas on their chin. They often decorate their tenkas with metal rings or tattoos.
Most recently, their scientific efforts have been focused, unsuccessfully, on harnessing black holes as a military weapon.
According to the Farscape Rolepalying Game by Alderac Entertainment, their home planet was Ilania. It was extremely close to the Luxan homeworld; the two stars are less than one light cycle from each other. It consisted of large, shallow oceans and moist swampy ground. A large animal population also inhabited the planet including numerous parasites and other disease carriers which threatened the early Ilanics.
Modern Ilania was covered with well-developed cities, many of which floated on the oceans or hovered above the swamps. Their massive capital of Jiri was a network of lights and towers, visible from orbit. Libraries were often the most impressive structures in these cities, though scientific facilities were also imposing.
Most Ilanic worlds are ruled by a council of six elected by popular vote. The supreme ruling body on Ilania is called the Central Council. It commands the Ilanic military. Ilanics of either gender could serve on a council. A new council member was elected every two cycles, each serving for twelve cycles.
Ilanics and Luxans shared many genetic traits, and mating across racial species was common. Most Ilanic researchers believe that massive interbreeding took place when the two species first encountered each other. A less popular theory, some scholars claim that either the Luxans or the Ilanics were a lost colony from early attempts at space travel.
The dangers of their planet prompted a technological advancement faster than that of most other races. And many Ilanics work as technicians, mechanics, doctors, or scientists.
Ilanics enjoy sharing their technology and allow others access to their achievements. They believe that by sharing information they establish dominance over them. However, they recently became more secretive and guarded due to their ongoing war with the Scorvians.
Luxans and Ilanics had a strong and ancient alliance, that has lasted for over one thousand cycles. Ilanics helped develop the Luxans' technologically while the Luxans taught the Ilanics martial skills.
