General Historical information:

The Nationette of Tinasia, Currently standing as the largest Neveran bound Nationette of the Titanian Empire, is the eldest of all of the Nationettes currently 912 years old and is the basis for which the Nationette system was founded. 

Conquered during the Elliran Genocide during the 15th century the Territory of Tinasia, eastern Renora and northern Nexus, was inducted into the then Federation of Titania, with the Tinasian majority territories given the special designation of Nationette.

At the time the concept of a Nationette was new, A territory within the Federation that mostly functioned as its own state was quite unheard of, and if any other group within the Federation had demanded or asked for such a thing the most likely response from the then Velire (the designation for elected leader.) would have likely ordered a deportation, but due to Tinasia's history and the entire reason behind the Federations invasion and then out of control Genocide of the former Ellira being the atrocities being committed against the Tinasian people, the Velire at the time felt somewhat obligated to give the Tinasian people some form of autonomy, resulting in the senatorial decree of the creation of the early Nationette system. 

Today this system is used across the entire Titanian Empire, though modified heavily, and while the Nationettes themselves no longer hold the autonomy they did when the system was first founded it is still exceptionally libertarian in comparison to the brutalist Unitary systems of most other Nations.

Tinasia due to its unique environment was also mostly spared the horrors of the war against Hell, and the vast majority of wars in Titanian history, though this did not spare the Nationette from the Long Night, even with its unique position to fend off any incursions, without the light of Belaara and the occasional orbital bombardment from a slain starship, the Nationette like all of mankind was still effected and lost 92% of its population.

Currently the Nationette of Tinasia, holds a population of 14 million, less than one fifth of what it once held, though Tinasia is not alone in this, as most of mankind is similarly depopulated.

Environment:

Tinasia is the home of a unique geological and meteorological phenomenon, known as Ever-Wets, the Nationette for as long as history has been able record only ever sees 5-9 days a year without constant rain, this is caused by the geyser fields of Roai, the most extreme geysers on all of Nevera, their water spouts reaching at minimum 2 Miles high, across the southern border in Northern Ervona combined with north bound winds that bring the mineral rich and scolding hot vapor the these geysers produce across the border into Tinasia, resulting in nearly constant and unending rain cover. The average temperature is 7 degrees Celsius in southern Tinasia and gradually rises to 16 degrees in Hackolite.

This leaves the majority of Tinasia completely inhospitable to outside flora, as the only plant-life to ever be recorded capable of surviving in Tinasia is native to Tinasia itself, The fauna are similar as most animal and insect life can't sustain itself under constant bombardment from the rain, though there are notable exceptions, such as the Renoran Bark Beetle and Hockolian Long Wing.

The Rivers in the majority of mainland Tinasia are completely devoid of all fauna however, the conditions within these rivers is impossible for the vast majority of life both flora and fauna combined, as these rivers at average reach speeds of 300 Miles per hour and have carved nearly 100 feet deep in certain locations, making them extremely hostile to life. Though this is not true in many places within far North Tinasia, Past central Nirea the rivers calm and become more akin to those located in the Nationette of Tessa or the Nationette of Listle.

The Tinasian Isles, Made up of the largest island Hackolite and its smaller siblings, are not as unique as the mainland of Tinasia other than in trade and economy. During the 20th and 21st century these islands were by far the easiest to trade with as unlike the mainland these islands were not plagued by constant rain and flooding, resulting in a large influx of Titanians and various minorities from the wider Kingdom of Titania to settle in the Nationette of Tinasia.
