Dorin is one of the most luxurious planets in the galaxy, though only few are able to enjoy it. The planet is located between two black holes, providing it with the most unusual atmosphere that has been proven to be very toxic to a majority of species throughout the universe. It is the home of the famed Kel Dor race. The Kel Dor, who have genetically been built to withstand such harsh elements, inhabit a majority of the planet’s surface. Due to this genetic structure, this also requires Kel Dor traveling away from Dorin to wear anti-ox masks to filter out the harmful oxygen atoms.

Much of the planets economy rests on technology and tourism. The planets surface is filled with natural resources, just as are many of the other planets surrounding Dorin in the system. Dorinian products are highly regarded in the galactic market and greatly valued throughout the galaxy. Though the harsh atmosphere is deadly to many beings, that hasn’t stopped a surplus of outsiders to stop on Dorin. The Kel Dor, being very accommodating hosts, provide numerous oxygen-rich facilities and buildings, allowing for a comfortable stay to all outsiders. In fact, a majority of all the buildings on Dorin have their own state-of-the-art oxygen enrichment systems. Kel Dor usually find it more suiting to be generous hosts, requiring them to wear their anti-ox masks on their home planet, than to have their guests be in discomfort.

The geography of the planet is the primary cause for the surge in the tourist industry. Three long mountainous regions make up a majority of Dorin's surface: the Ezion Mountains, which covers much of the western portion of the planet; the Ukric Mountains, which are clustered together in the northern region; and the Dorel Mountains, which are located in the east. The peak of Mount Knor, one of the more scenic areas of the planet, is located in Dorel Mountains, near the tourist city of Tadmor. The capital city of Tarsus lies in a low forest valley between the Ezion and Ukric Mountains. The area is known for its surplus of Kand trees, rare trees in which only inhabit Dorin and produce a delicious fruit. Forest regions also inhabit most of the north, containing Zand trees, which are the trees that are often used in manufacturing.

In the past, the Dorin system was relatively self-sufficient, answering to its own planetary government that governed Dorin as well as the surrounding planets in the system. The government, known as the Kel Dor Confederacy, ran efficiently and smoothly until, with the help of outside influence, a dreadful battle split the planet’s population in two, leaving the world in disorder and chaos. This marker was known as the “Royal Purge”.

It all began several hundred years ago, when the ruling monarch of Dorin was Sultan Barkos Talmon, son of Harhur Talmon. The Talmon family had been the ruling dynasty of Dorin for countless years, passing on the throne from generation to generation. Barkos was a great nobleman, as well as a divine leader. He rarely worked for his own personal gain, always working for the good of the Kel Dor. It came time for him to marry, and his father, Harhur, arranged his marriage to Juhaz, who later born him a son, Nebo Talmon. Barkos, though, was deeply unhappy, for his love went out to another woman, Eli Koon, daughter of Dorinian noble. Eli later gave birth to Barkos’ son, Jaala Koon, who kept his mother’s last name to hide him from the Dorinian public. Barkos loved both Eli and Jaala, and became to despise Juhaz and Nebo, who became power-hungry and corrupt. Later, at the crowning ceremony where the monarch passed down his ruling powers to his heir, Barkos shocked the Dorinian populace by revealing his son Jaala and naming him Sultan over Dorin, denying it to Nebo, the rightful heir. The Talmon family, along with their supporters, was outraged, while the other half of the population rejoiced. The Kel Dor Confederacy was thus split in two, beginning on non-ending clash known as the “Great Conflict”.

As years passed, the Kel Dor Confederacy unified once more. The Great Conflict was nowhere near over, but it had subsided. The Talmon family and their supporters lived on, tolerating the Koon dynasties control while they waited for the time to strike once more. Around 350 years passed when the Talmon’s finally made their move. Gaining support and resources from outside investors who wanted in on the Dorinian economy, the Talmon family, along with thousands of armed supporters, stormed the Sultan’s palace, killing all who stood in their path to the throne room. They captured Nekoda Koon, the Sultan of that period, and brought him out to the front of the palace. There, Zaccai Talmon, the heir in the line of Nebo Talmon, struck down Nekoda Koon, claiming the throne for himself. With that the Talmon clan struck down all members of the Koon family. Rumor has arisen though that the dynasty was not completely destroyed, stating that through the efforts of a few loyalists, the son of Nakoda was safely transported off of Dorin. The Talmon’s took over immediately and began persecuting Koon followers. Many went into hiding, but most were captured and became slaves. The Talmon’s had became extremely cruel and malicious. All open opposition was crushed. Thus was known as the “Royal Purge”.
