Cona is the only planet within the Teke Ro system. Its relatively hot temperatures and somewhat odd atmosphere make it an uncomfortable place for any except for the indigenous species. Cona's atmosphere is composed mostly of a mixture of nitrogen and hydrogen. Small amounts of ammonia vapor can result from the high concentration of these two elements, an irritating characteristic for non-Arcona. The thin supply of oxygen in the air is supplemented by an extraordinary amount of it within the ground.
The plant life of Cona is unique as the high temperatures of the planet should cause the plants to wither from lack of moisture. Interestingly, the plants have evolved to draw in the ammonia vapor from the air, extract out the hydrogen and mix it with the oxygen underground to form water. These underground water sources are valuable to the Arcona as there is actually little free water in the equatorial belt. The forests that have survived on the planet are home to several species of animals that the Arcona hunt out of necessity. Such areas are considered unsafe for younger members of the race as everything from hunter traps to carnivorous plants await any who wander aimlessly through them.
Cona is the homeworld of the Arcona, a reptilian race with some humanoid characteristics. They have evolved to easily survive and even depend upon the atmosphere of their world as they can take in and easily assimilate the ammonia vapor within the atmosphere. After the discovery of Cona by Old Republic ships an interesting problem arose for the inhabitants: salt. It seems that the Arcona are highly addicted to salt and in return, it is detrimental to their biology. Salt is considered an illegal substance on the planet of Cona and any nearby Arcona colonies and as a result, all ships bearing foodstuff are searched diligently in order to stop salt smuggling.
