Kavla is a heavily urbanised oceanic world in the NGC 5986 cluster (also known as the Korjes Cluster). Home to the amphibious Th'ega and their Federation, Kavla boasts a diverse range of fauna and flora such as the aforementioned Th'ega and the Axsti vine. Kavla's high population of 49 billion is spread mostly along the equatorial belt of cities and towns, with a tenth of the overall population spread across both the north and south poles. The capital city of Li'ion - a sprawling iceberg city that extends from the surface to the seafloor - is well-known throughout the Milky Way as a gleaming metropolis packed with circular boulevards and some of the largest urban markets in the galaxy. A single market (the Xrestol Asthetol) takes up a whopping four tiers (or approximately 178 square kilometres) of Kavla's largest city, Li'ion. Kavla is also a popular planet among First Civilisation researchers due to the strong evidence that it was visited by the aforementioned nation's scientists. It is thought that many experiments were conducted on Kavla, which helped influence Th'ega culture.
Kavla is a warm oceanic world orbiting the young orange dwarf Ochi'an - the B star of the Ochi'an / Kari'an binary. One Kavlan year is equivalent to approximately 105 standard days long and the rotation period is just over 14 hours. Kavla has a mass of 4.72 Earths giving it its somewhat uncomfortable surface gravity of 1.6G. Carbon dioxide is the dominant gas in the atmosphere, making up as much as 44.8% of all the gases present. Oxygen comes up in second at 38.6%, with sulfur dioxide following behind at 16.4%. Such a toxic atmospheric composition is not uncommon in the universe but is unheard of on most intelligent life-bearing worlds. However, most pressurised Kavlan cities have finely-tuned atmospheric compositions that allow for both Th'ega and other species to breathe (almost) unaided.
Forming just over 679 million years ago, Kavla is a very, very new planet in the universe's history. A mere 2 million years later, the earliest life on Kavla appeared. It is currently widely-accepted that the first Kavlan organisms came from a life-bearing asteroid that impacted Kavla around the same time. That life slowly evolved over time, producing the many species that live on Kavla.
